How to calculate acres of land on a plot? What is a hundred? A hundred square meters of land is how much, or what, can fit in such an area.

In the life of each of us, various legal issues may arise, for example, we can enter into a contract for the sale and purchase of a land plot or a lease agreement.

First of all, any person will be interested in how many square meters are in one hundred square meters and how to calculate it correctly. Let's talk about this in more detail.

How to calculate - using a specific example


A weave is a square with a length and width of 10 meters, i.e. 10 meters * 10 meters = 100 m2 = 1 weave. In practice, this is approximately 12-14 human adult steps. Using the same analogy, you can calculate a hectare: 100 square meters = 0.01 hectares = 0.02471 acres.

Example: A plot of 9 acres - this means a plot of 30 by 30 meters, or 20 by 45 meters, or 25 by 36 meters.

Origin of the word "weave"


The word “weave” comes from the concept of one hundredth of something. In this case, this is one hundredth of one hectare; in the example, it would look like this: 0.01 hectares.

Now on our land the entire area is measured in hundreds. And not only the land is measured. The following example can be used: a tractor driver needs to process 30-35 acres per day.

Why are calculations needed?

Thanks to these calculations, you can find out the size of your house or garden. The cost of the plot in the transaction will depend on the amount of land. Knowing the size of the plot's land in acres, you can plan the development of other buildings on your land.

Abroad, it is customary to measure land using other measures. Before the introduction of the metric system in Rus', ancient Russian measurements were used. Previously, land was measured in tithes, and a hectare included twelve such tithes.

Yes, and on our land they began to measure land in hectares and acres not so long ago. This happened from the beginning of the October Revolution and the formation of the Soviet Socialist Republic.

But even in our time, not all countries measure land in hundreds. And in the territories that were under the rule of the Ottoman Empire, the land is measured by Dunam. In Thailand, the measure of earth is called paradise.

The conclusion can be drawn as follows: one hundred square meters is one hundred square meters. The concept of “weave” is quite convenient; it arose about 100 years ago and its main property is the measurement of land.

The value is quite convenient and simple, does not require complex calculations. This calculation can be performed by anyone. It is enough to take a certain number of steps and you will see the allocated area.

This online calculator helps to calculate, determine and calculate the area of ​​a land plot online. The presented program can correctly suggest how to calculate the area of ​​land plots of irregular shape.

Important! The important area should fit approximately into the circle. Otherwise, the calculations will not be entirely accurate.

We indicate all data in meters

A B, D A, C D, B C— The size of each side of the plot.

According to the entered data, our program performs online calculations and determines the area of ​​land in square meters, acres, acres and hectares.

Method for determining the size of a plot manually

To correctly calculate the area of ​​plots, you do not need to use complex tools. We take wooden pegs or metal rods and install them in the corners of our site. Next, using a measuring tape, determine the width and length of the plot. As a rule, it is enough to measure one width and one length, for rectangular or equilateral areas. For example, we have the following data: width – 20 meters and length – 40 meters.

Next we move on to calculating the area of ​​the plot. If the shape of the area is correct, you can use the geometric formula for determining the area (S) of a rectangle. According to this formula, you need to multiply the width (20) by the length (40), that is, the product of the lengths of the two sides. In our case S=800 m².

After we have determined our area, we can determine the number of acres on the land plot. According to generally accepted data, one hundred square meters is 100 m². Next, using simple arithmetic, we will divide our parameter S by 100. The finished result will be equal to the size of the plot in acres. For our example, this result is 8. Thus, we find that the area of ​​the plot is eight acres.

In the case where the land area is very large, it is best to carry out all measurements in other units - in hectares. According to generally accepted units of measurement - 1 Ha = 100 acres. For example, if our land plot, according to the measurements obtained, is 10,000 m², then in this case its area is equal to 1 hectare or 100 acres.

If your plot is of irregular shape, then the number of acres directly depends on the area. It is for this reason that, using an online calculator, you can correctly calculate the S parameter of the plot, and then divide the result by 100. Thus, you will receive calculations in hundred square meters. This method makes it possible to measure plots of complex shapes, which is very convenient.

Total information

Calculation of the area of ​​land plots is based on classical calculations, which are performed according to generally accepted geodetic formulas.

There are several methods available for calculating the area of ​​land - mechanical (calculated according to the plan using measuring palettes), graphic (determined by the project) and analytical (using the area formula based on measured boundary lines).

Today, the most accurate method is deservedly considered to be analytical. Using this method, errors in calculations usually appear due to errors in the terrain of the measured lines. This method is also quite complicated if the boundaries are curved or the number of angles on the plot is more than ten.

The graphical method is a little easier to calculate. It is best used when the boundaries of the site are presented in the form of a broken line, with a small number of turns.

And the most accessible and simple method, and the most popular, but at the same time the biggest error is the mechanical method. Using this method, you can easily and quickly calculate the area of ​​land of simple or complex shape.

Among the serious disadvantages of the mechanical or graphical method, the following are distinguished: in addition to errors in measuring the area, during calculations an error is added due to the deformation of the paper or an error in drawing up plans.

When registering the purchase of land plots (plots), as a rule, it turns out that most buyers have no idea what a certain, seemingly quite familiar value means, and the question of how much is a hundred square meters can often be heard even in the cadastral chamber . In such cases, you should immediately explain to the buyer at the offer stage that plot sizes in our country are not usually calculated by meters. In meters it is good to calculate only the size of a small greenhouse.

However, for a person who rarely encounters specific calculation information, and land accounting measures are far from colloquial concepts, it is not at all difficult to make a mistake. Moreover, many people think that the word weaving is an outdated concept, unlike, for example, a cube, which they consider a modern unit of measurement, forgetting that these words refer to completely different measures. How to calculate a vegetable garden in cubes, and how many acres of land is in meters (m³)? It is because of such ambiguities between people that problems arise in calculations. And in order to avoid them, you should have a clear understanding of units of measurement and sizes.

By the way, about outdated concepts and measures. The table below shows ancient units of area measurement in Rus'.

Basic measures of land area

So, first of all, it’s worth understanding that weaving is a word that is derived from the numeral 100, in our case, it is a measure of the area of ​​a plot of land. And this measure appeared relatively recently, about a hundred years ago, before this, measurements of land plots were carried out in arahs, and the word weaving was used as a common simplified concept, and how many meters of land in a hundred square meters was not previously understood.

In modern Russia, this is an official measure, and in all official ones, the area of ​​a plot is determined in hundred square meters, and it is precisely per hundred square meters that the price is set.

Numbers are numbers, they can be displayed on a special calculator or online converter, but visually, how much is one hundred square meters of land? How much is this? Is this area enough to build a house and grow a vegetable garden? For those who are not regulars at summer cottages, it will be easier to convert hundreds to meters (square, of course). And then it will become clearer how many square meters 1 hundred square meters covers. Imagine a room in an apartment with an area of ​​one hundred square meters. What, is it a little complicated? Then just add your two “kopeck pieces” together, and you’ll get exactly one hundred square meters. On the one hand, this is oh so much... for an apartment, but for a plot of land - not very much, there is enough space to put a booth, but you can forget about the vegetable garden. And 4 acres of land, how many square meters is that, and is it enough for a farm?

Many of us remember from the times of the USSR that city residents received dacha plots of four or six acres for personal farming, growing vegetables and fruits. Even on 4 acres, houses and small vegetable gardens with potatoes, bushes, several apple trees and outbuildings coexisted quite well.

Real summer residents knew exactly how many square meters in one hundred square meters of land, since they calculated everything meticulously in order to fit all their dreams on the allocated plot.

And 6 acres, this was the height of chic, even noisy large companies gathered in such areas for picnics, there was enough space to set up a flower garden with beautiful paths, and some even kept small animals in the form of chickens and pigs.

Grain fields

Plots of land are also used for agricultural purposes, but the scale is different and the measurements are per hectare. Hectares are also used to measure forested areas and, more recently, elite family estates.

Table of conversion of metric units to precinct units

Based on the above, we will now know exactly how many meters are in 1 hundred square meters of land.


Usually the old generation knows about all this. And they have long been able to calculate the number of meters per hundred square meters. Representatives of the younger generation, most often, have not heard the word “weaving” at all, and calculation methods are unknown to them. Indeed, in official land documents it is not customary to use this concept at all; there the area is calculated only in hectares, not even in acre. So, what is one hundred square meters of land and how to calculate?

Simple shape area

There are different plots of land. They are usually simple geometric shapes: squares or rectangles. But there are exceptions when the section is a trapezoid or parallelogram. On a plot of land that has a rectangular or square shape, it is much easier to calculate one hundred square meters of land. Only one geometric formula will help you understand everything. Formula for the area of ​​a rectangle or the area of ​​a square.


An area of ​​one hundred square meters is the size of a hundred square meters.

As you know, special objects are used to calculate the area of ​​land. They are found among agronomists, cartographers and other workers who deal with such measurements. You can say that you are one of them. But in order to calculate one hundred square meters of land, you don’t need to worry about the lack of any complex tools. They simply won't be needed.

All you need is:

  • any four pegs;
  • tape measure (not too short);
  • pen and notepad.

Install pegs in all corners of the plot of land. From peg to peg, measure all the boundaries of the site with a tape measure. If all sides are the same length, then it is a square. If the two short sides are equal, as are the long sides, then it is a rectangle. Record your results in a notepad. Let's say one side turns out to be 30 meters, and the other - 40. Then you need to multiply these numbers by each other. The result was 1200 square meters. One hundred square meters is 100 square meters. Divide 1200 by 100, we get the number 12. That’s it, the size of the plot of land was 12 acres. If the sides are the same (square), then multiply any two of them by each other and divide by one hundred.

You can not use a tape measure, but build a wooden meter compass with your own hands. Starting from the peg, meter by meter, walk and count. It is important that the distance between the ends of the legs of the compass is exactly one meter! One hundred square meters of land is 100 square meters.

Areas of complex shape

Sometimes it happens. When the area has a complex shape (not a square or a rectangle), for example, a trapezoid or, in general, a circle. Here other geometric formulas will come to the rescue. For example, a section has the shape of a parallelogram.

You only need to find the length of the longer side. But now we have to find the height. You will get the area if you multiply the length by the height. This is the simplest way to calculate the area of ​​a parallelogram. The same applies to calculating the area of ​​a rhombus.


The height should be perpendicular to the larger side. That is, form an angle of 90 degrees with it, at least by eye.

If you have a trapezoid, then you will need to find the lengths of its bases. The bases are two parallel lines. Only then look for height. You can find the area using the formula: half the sum of the bases is multiplied by the height. On a calculator it will look like this: base plus base, multiplied by height, and multiplied by 0.5. That's it, there is space.

Round areas exist, but these are very rare. You need to find the center of the circle. Radius is the distance from the center to the edge of the circle. You can find the area using the formula: 3.14 (Pi) multiply by the length of the radius squared (multiplied twice by itself).

Ellipsoidal (oval) areas are just as rare. Even more difficult, you will have to look for the center of the oval and the length of the axes. Multiply half of the major axis by half of the minor, and then multiply by 3.14. Ready.

There are quadrangular areas where the sides are all different. That is, for example, one is 19 meters, another is 27, the third is 30, and the fourth is 50. It is best if one angle is right. You'll have to measure all sides. There, most often, sines and cosines are used, which cannot be calculated on site. However, there are online calculators that allow you to search for the area of ​​such quadrilaterals on all sides.

When the area is too large, the size is calculated in hectares. 100 acres = 1 hectare = 10,000 square meters.

Weave and area

You can find out the size of the plot in acres from the documentation or measure it yourself by picking up a meter.

If the number of acres is known

If you know the number of acres of a summer house or garden, but you suddenly want to calculate the area of ​​the plot, then use the reverse calculation. For example, there are six acres. Multiply six by one hundred. It turns out 600 square meters - this is the area. If the size of the plot is 10 acres, then in meters it will be 1000.

When there is no data

If you do not know either the number of acres or the area, then in this case you will need to find out, of course, only the area. Also learn: pegs, side measurements, and arithmetic. Both the area and the number of acres will be known, if you want.

You can find out how many meters are in one hundred square meters of land using an online calculator by entering the number of hundred square meters there. For example, 63.5 acres. The area will be 6350 square meters.

The word “weaving” is widely used in informal communication between people, especially those associated with land plots. Yes, yes, what gardener doesn’t know how many acres of land are on his plot? The old generation remembers exactly and by heart about their three or six hundred square meters!

And although in official land documents it is required to indicate the area of ​​plots only in hectares, especially when buying and selling, it is still more common for people to hear and count land for a garden in acres.

For interaction with cadastral authorities, the area of ​​the plot is in hectares (ha). In this material, we propose to understand the terminology and units of land measurement, find out what a “weave” actually is and what is its relationship to a hectare.

How many square meters in one hundred square meters?

Whatever the reasons for clarifying the area of ​​your land plot, the dimensions of which you know in acres, the classic conversion from acres to meters will proceed according to the following scheme:

an area of ​​1 hundred square meters = 100 square meters (1 hundred square meters = 100 m2).

How to measure the area of ​​a plot of land with a simple shape?

It is correct to start measuring by measuring the sides of the area. Having hammered pegs into the corners of the area, using a tape measure, take accurate measurements of their length and width. If the area is of the correct geometric shape, then only two sides are needed - length and width. It is better to write down the measurement results in a notepad or enter them into a computer.

But if your site turns out to be asymmetrical, then you need to take measurements of all four of its sides and angles in degrees, or the length of the diagonals - also for recording.

If your vegetable garden is of irregular shape (NOT a square or NOT a rectangular plot), then the method of measuring a plot of land is a little more complicated than multiplying the length and width, but it is quite possible for an ordinary person without special education.

How to determine the size of a plot in square meters

To make the calculation as accurate as possible, you will need a tape measure, several pegs and a notepad to record the measurement results. The entire course of the required calculation follows the laws of the school geometry course, which states that to accurately determine the area of ​​a rectangular figure, you should multiply its width by its length, for example:

  • A - length, m;
  • B - width, m;
  • S - area, m2;

For example, if the length of your plot of land is 70 meters and the width is 40 meters, then the area can be calculated as S = 70m * 40m = 2800 m2, that is, in this case, the area of ​​your land is 2,800 square meters.

Considering that 1 hundred square meters is equal to 100 m2, we go the opposite way to convert the data from meters to hundred square meters. This will allow you to obtain correct results of measuring the area of ​​a given land plot. When calculating the number of square meters in a hundred square meters, you need to divide the resulting result by 100, for example:

  • plot area - 1000 m2;
  • 1000 m2 divided by 100;
  • number of acres - 10

If your plot has an irregular geometric shape, but you have correctly calculated its area in square meters, the method for calculating the size in acres remains the same. Large areas are usually measured in hectares, each consisting of 10,000 square meters or 100 acres.

Calculation of land area online using a calculator

Today there are quite a few services and online calculators on the network that allow you to calculate the area of ​​a land plot; just use one of the search engines, for example Yandex.

Keep in mind that the online area calculator will need the exact dimensions of all sides of the plot in meters for its algorithm to accurately calculate the area of ​​your plot of land.

An irregularly shaped area is more difficult to calculate, and the dimensions of the sides alone will not be enough to calculate the area of ​​a complexly shaped area. Here you will need to know the dimensions of all sides of the garden, and the size of the diagonals. It’s a little easier if one of the corners of the plot is 90 degrees.

Here is an example of calculating acres of land for a complex-shaped dacha plot:

Dimensions of the sides of the land plot, in meters

  • Side A-B = 69 meters,
  • Side B-C = 46 meters,
  • Side C-D = 87 meters,
  • Side D-A = 35 meters,
  • Lower left corner is straight (90 degrees)

Using these data, you can determine the lengths of diagonals B-D and A-C, and calculate the area of ​​the plot = 3035 square meters (or 30.35 acres).
