Convert square meters to hectares. Unit Converter Convert square meter to hectare. What is a hundred and a hectare

What is weaving, ar, hectare, square kilometer? How many hectares, square meters and kilometers in one are (hundred) of land? How many square meters, kilometers and acres are in one hectare of land? How many acres, hectares and square meters in one square kilometer?

At school, each of us studied the units of measurement of the area of ​​land. We knew what an ar, a weave, a hectare were, and how many square meters they contained. Today, many adults have already forgotten how to perform such fairly simple computational operations. This article will come to the aid of such "dunno" people.

How many square meters in 1, 10, 100, 1000 acres: table

• Weaving is a unit of measurement for the size of a plot, which is often used in a summer cottage or agriculture. In science, it is customary to use an analogue of a hundred - ar.
• Based on the name of this measure, one can already guess that we are talking about hundreds of meters.
• Indeed, one hundred square meters is equal to 100 m2.
• In other words, one weave will be equal to the area of ​​​​a square with sides of 10 m.
• Accordingly, in ten acres there will be 1000 m2.
• 100 acres contain 10,000 m2, and 1000 acres contain 100,000 m2.
• In other words, to calculate how many square meters are in a given number of acres, you need to multiply the acres by 100.

How many acres in 1, 10, 100 square meters: table

• To calculate how many acres are in square meters, you need to divide the given number of square meters by 100.
• Thus, in 1 m2 there are 0.01 weave, in 10 m2 - 0.1 weave, and in 100 m2 - 1 weave.

What is a hectare of land?

• A hectare is a unit for measuring the size of a plot, which is equal to the area of ​​a square with sides of 100 m. A hectare, like a weave, is mainly used as measuring units only in agriculture and summer cottages.
• The designation of a hectare looks like "ha".
• One hectare is equal to 10,000 m2 or 100 acres.

How many square meters in 1, 10, 100, 1000 hectares: table

• In order to calculate how many square meters in a given number of hectares, you need to multiply the number of hectares by 10,000.
• Thus, there are 10,000 m2 in 1 ha, 100,000 m2 in 10 ha, 1,000,000 m2 in 100 ha, and 1,000,000 m2 in 1000 ha.

How many acres in 1, 10, 100, 1000 ha: table

• To calculate how many acres corresponds to a given number of hectares, you need to multiply the number of hectares by 100.
• So, in 1 hectare there are 100 acres, in 10 hectares - 1000 acres, in 100 hectares - 10,000 acres, and in 1000 hectares - 100,000 acres.

How many hectares in 1, 10, 100, 1000, 10,000 acres, square meters: table

• To calculate how many hectares are contained in a given number of acres, you need to divide the number of acres by 100.
• And in order to carry out such calculations with square meters, it is necessary to divide their number by 10,000.
• So, in 1 acres there are 0.01 ha, in 10 acres - 0.1 ha, in 100 acres - 1 ha, in 1000 acres - 10 hectares, in 10,000 acres - 100 hectares.
• In turn, there are 0.0001 ha in 1 m2, 0.001 ha in 10 m2, 0.01 ha in 100 m2, 0.1 ha in 1000 m2, and 1 ha in 10,000 m2.

How many square kilometers are in 1 hectare?

• A square kilometer is a unit of land area, equal to the area of ​​a square with sides of 1000 meters.
• There are 100 hectares in one square kilometer.
• Thus, to calculate the number of square kilometers in a hectare, it is necessary to divide its given number by 100.
• So, in 1 hectare there are 0.01 sq. km.

• Arom is a unit of measure for the size of a plot, equal to the area of ​​a square with sides of 10 m.
• In other words, ar is equal to a hundredth.
• In 1 are there are 100 m2, 1 weave, 0.01 ha, 0.0001 sq. km.

How many ares are in one hectare?

There are 100 ares in one hectare, just like acres.

Area units: Video

Formally, the area in Russian Federation expressed in square meters, as well as multiples and submultiples of them. And in life we ​​often hear numbers with the addition of “weaving”, “hectare”, and for those who graduated from school a long time ago, the question arises: how much m2 is in 1 hectare? And a hundred?

Some official data on the use of the term "hectare"

Why, in the presence of such a unit as a square meter (abbreviated as m 2 or sq. M.), square kilometer (abbreviation - km 2), do we often hear the names of a hectare, weave? You can’t use foreign units, there is the SI system, you have to use it.

The thing is, it's not a foreign term. There are off-system units that are allowed to be used on a par with standard ones. And a hectare belongs to such non-systemic units, he has a considerable company - non-systemic, for example, are an hour, a minute, a kilowatt-hour (you pay electricity networks for it) and a ton.

In Russia, GOST 8417-2002 is relevant, it says: “4.1 Units are subject to mandatory use international system units, as well as decimal multiples and submultiples of these units. A hectare (designation Ha, in Russian Ga) is indicated in Table 2 of the State Standard as an example of a derived unit, its international (m 2) and Russian (m 2) designations are given.

So the term is quite official, and it can be used without restriction.

Find out how many m2 in 1 ha. To do this, let's look at the dictionary: One hectare is the area of ​​a square with a side of 100 meters. To calculate the number of square meters in a hectare of land, you need to remember school mathematics and multiply 100 by 100. A hectare is 10,000 m 2.

In the strict and precise language of mathematics, this is expressed by the equality: 1 ha \u003d 100 ar \u003d 10,000 m 2.

The international SI system is not a dogma; it also changes frequently. In 2019, the definitions of the last basic units have changed, and since May, absolutely all units do not depend on samples and are determined by exact formulas through the values ​​of physical constants. Previously, a kilogram, for example, was tied to a standard, now it is a rather complex formula.

Is one hectare a lot or a little?

It depends on what needs to be calculated. If we are talking about the area of ​​a leaflet on the table - a hectare is too large, it is inconvenient to write down. This option uses square centimeters. If we compare the area of ​​countries - too small, the number will be very large. This is where square kilometers come into play.

Although due to the fact that the hectare is the standard of measurement in agriculture - the area of ​​agricultural land, the forests of countries are measured in hectares. So they write: "More than 9% of the entire land area of ​​the Earth is occupied by arable land, which is approximately a little more than 1.3 billion hectares." Or: "Forests in Russia occupy 809 million hectares."
In the UK and the US, area is still measured in acres.

Let's look at illustrative examples:

1. The basketball court measuring 28 by 15 meters has an area of ​​420 square meters (4.2 acres, 0.042 hectares).
2. Moscow Red Square in the capital of Russia is 2.5 hectares (330*75 meters).
3. Times Square in New York - 6.6 hectares.
4. Central Park - 341 hectares.

Where are square meters and acres used, and where are hectares and square kilometers

There are a million square meters in a square kilometer. m. They denote the area of ​​countries, large cities and continents. In hectares and thousands of hectares, the area of ​​\u200b\u200bthe same type of large and medium plots is measured - all arable land in the region, the area of ​​\u200b\u200bthe Amazon forest, the area of ​​\u200b\u200bwheat or rapeseed. Private small plots, gardens and orchards in villages, towns, small towns are denoted by acres, the area in acres is written by publishing ads for sale in a newspaper and on the Internet. It is more correct to write not “hundreds”, but ar - this is how the area of ​​\u200b\u200ba square with a side 10 meters long is written. Its area (10 * 10) is exactly one hundred square meters, it is easy to remember, thanks to popular name"weave", and this is also a unit of area allowed by the standards.

The term "ar" was introduced in France in the 18th century and comes from the French word "are", meaning "plain, area, area, field." The word "hectare" is a multiple of the word "ar" and is formed by the prefix "hecto" - "hundred". Based on the origin of the word, a hectare is “one hundred plots of 100 squares”.

In square meters, they measure houses, apartments, the area of ​​\u200b\u200bplots for communications, the areas of warehouses, offices and shops.

There are also derivatives of the basic unit ar. Dekar (aka dunam, stremma), equal to 10 acres or a thousand square meters, is used in Iraq, Libya, Syria, Greece. Centiar, equal to 1 square meter - literally "a square with a side of 1 meter", is used to a limited extent in Cameroon and Italy.

Using units of different sizes is better and more convenient than always specifying square meters:

• area of ​​countries and regions in square kilometers;
• fields and forests in hectares;
• kitchen gardens, house adjoining plots and gardens in acres;
• houses, and apartments in square meters.

Units for indicating land area in Russia in the 19th century

If we were to ask a peasant in Russian Empire XIX century, how many acres or hectares in his land allotment - he would not understand us. At that time, the area was measured in square arshins, fathoms and tithes. There was also a “mop”, it was believed that 10 hay was collected from the tithe.

1 square sazhen \u003d 4.55 m 2.

1 tithe is equal to 1.093 hectares.

One tenth of a tithe was called a mop.

The tithe, in which the land was measured, was only a little more than a modern hectare. So if you see it in the book, you will roughly know how to count: “You know that wood that is behind our levada, and, surely, you know a wide meadow behind the same forest: there are almost twenty acres in it” (quote from Gogol’s book "Evenings on a Farm Near Dikanka"); large meadow, approximately 21 hectares. How much will it be in acres and square meters? We count in acres: 21 * 100 \u003d 2100 acres. Two more zeros will be added in square meters. 210000 m2. Can you imagine thirty football fields? It is easier to imagine a rectangle of 300 by 700 meters, which is just 21 hectares.

The allotment of the peasants, from which they paid dues, was the size of several acres.

With the help of this table and calculator, you can always calculate how many square meters in a hectare.
Conversion table - how many m2 in 1 ha

How to calculate how many square meters a plot, how many hectares and what is the area of ​​​​a plot in acres

If you want to change the size of the plot by buying land from a neighbor or adding to your vacant lot neighboring plot- You can't do without specialists!

To calculate the approximate area of ​​a rectangular area in acres, you need to measure the two sides with a tape measure, a laser rangefinder or a sazhen and multiply their length in tens of meters. The plot area of ​​20 by 30 meters is calculated as 2 * 3 and is equal to 6 acres.

For a quick calculation in hectares, we multiply hundreds of meters of side lengths: a plot of 300 by 900 has a size of 27 hectares.

If the numbers are not very even, feel free to use a calculator. Multiply the length by the width in meters, divide by 100 to get the area in ares. Divide by 100 again, that's hectares.

If the plot is irregular in shape, for the calculation it is necessary to divide the plot into rectangular, triangular, trapezoidal pieces and calculate the sum of their areas.

Examples of calculations - how many square meters in a hectare of land:

1. The mowing is 30 meters wide and 80 meters long. The mowing area is 30*80=240 m2. This is 240/100 = 2.4 acres (ara) or 2.4/100 = 0.024 hectares.
2. Next to the mowing stands a farmer's house, its dimensions are 10 by 20 meters. The area of ​​the plot occupied by the house is 200 m 2, 0.2 acres or 0.002 ha.

Accurate calculation of the plot area

Unfortunately, the edges of the plots are rarely even, and the corners - rectangular. If the area is really important, you will either have to master the tools of a surveyor, or hire a specialist. There is no alternative to a specialist if you are going to sell or perform some other actions with your site, and you do not have a cadastral passport. In this case, you need to contact the experts. They will take measurements on the ground, if necessary, satellite imagery and draw up documents that will indicate exactly how many square meters, acres and hectares are at your disposal.

In addition, the prescription for the mandatory use of units SI set out in the interstate standard in force in Russia GOST 8.417-2002, which lists the units of physical quantities permitted for use, gives their international and Russian designations and establishes the rules for their use.

International system of units SI - the most used system of units in the world both in everyday life and in science and technology. Currently SI adopted as the main system of units by most countries of the world and is almost always used in the field of technology, even in those countries in which traditional units are used in everyday life.

SI defines 7 basic units of physical quantities and derived units (abbreviated units SI or units), as well as a set of prefixes.

SI also establishes standard abbreviations for units and rules for writing derived units.

Basic SI units

• kilogram (kg, kg) - unit of mass
• meter (m, m) - unit of length
• second (s, s) - unit of time
• ampere (A, A) - unit of electric current strength
• mole (mol, mol) - unit of the amount of a substance
• candela (cd, cd) - unit of luminous intensity
• kelvin (K, K) is 1/273.16 of the thermodynamic temperature of the triple point of water:
  1. degree Celsius (°C) is a common unit of temperature used in the SI along with the kelvin

Conversion to degrees Celsius:

As part of SI the base units are considered to have independent dimensionality, that is, none of them can be derived from the others.

Derived units are obtained from base units using algebraic operations such as multiplication and division. Some of the derived units in SI assigned their own names, for example, the unit radian.

CI prefixes must be used before unit names. They mean that the unit must be multiplied or divided by a certain integer, which is a power of 10, the number of times.

Decimal prefixes serve to reduce the number of zeros in the numerical values ​​of physical quantities.

For example:

• the prefix "kilo" means multiplying the original unit meter per 1000 (kilometer = 1000 meters)
• the prefix "milli" means multiplying the original unit meter by 10 -3 (millimeter = 0.001 meters)
• the prefix "deci" means multiplication of the original unit meter by 10 -1 (decimeter = 0.1 meters)

Area units

Concerning area units that are derived from the basic unit of length meter, the list looks like this:

• length
  1. unit of measure - meter
  2. designation (Russian) - m
  3. designation (international) - m
• square
  1. unit of measurement - square meter
  2. designation (Russian) - m 2
  3. designation (international) - m 2

Explanation

Meter - the length of the path traveled by light in a vacuum in a time interval
1/299792458 seconds (XVII General Conference on Weights and Measures ( CGPM), 1983, Resolution 1).

XXV CGPM, held in 2014, decided to continue work on the preparation of a new revision of the SI, including a redefinition of the meter, and tentatively scheduled to complete this work by 2018 in order to replace the existing SI with an updated version at XXVI CGPM in the same year.

A common system in Russia for measuring land areas (off-system in relation to SI)

• 1 weave \u003d 10 m x 10 m \u003d 10 m x 10 m \u003d 100 m 2
• 1 hectare \u003d 1 ha \u003d 100 m x 100 m \u003d 10,000 m 2 \u003d 100 acres
• 1 square kilometer = 1 km 2 = 1000 m x 1000 m = 1 million km 2 = 100 ha = 10,000 acres

Inverse units

• 1 m 2 \u003d 0.01 acres \u003d 0.0001 ha \u003d 0.000001 km 2
• 1 weave \u003d 0.01 ha \u003d 0.0001 km 2

Area units conversion table

• Hectare

a unit of area in the metric system of measures used to measure land.

Abbreviated designation:

• Russian - ha
• international - ha

1 ha is equal to the area of ​​a square with a side of 100 m

The name "hectare" is formed by adding the prefix "hecto ..." to the name of the area unit " ar»:

1 ha \u003d 100 ar \u003d 100 m x 100 m \u003d 10,000 m 2

• Ar - a unit of area in the metric system of measures, equal to the area of ​​​​a square with a side of 10 m:
  
  1. 1 ar \u003d 10 m x 10 m \u003d 100 m 2
  2. 1 tithe = 1.09254 ha

• Acre

land measure used in a number of countries using the English system of measures (Great Britain, USA, Canada, Australia, etc.).

1 acre = 4840 square yards = 4046.86 m 2

The most commonly used land measure in practice is hectare - the abbreviation ha:

1 ha = 100 are = 10,000 m 2

In Russia, a hectare is the main unit for measuring land area, especially agricultural land.

On the territory of Russia, the unit "hectare" was put into practice after the October Revolution, instead of the tithe.

Old Russian units of area measurement

• 1 sq. verst = 250,000 sq. fathoms \u003d 1.1381 km 2
• 1 tithe = 2400 sq. fathoms \u003d 10,925.4 m 2 \u003d 1.0925 ha
• 1 quarter = 1/2 tithe = 1200 sq. fathoms = 5462.7 m² = 0.54627 ha
• 1 octopus \u003d 1/8 tithe \u003d 300 square sazhens \u003d 1365.675 m 2 ≈ 0.137 ha

The area of ​​land plots for individual housing construction, private household plots is usually indicated in acres

One hundred- this is the area of ​​\u200b\u200ba plot measuring 10 x 10 meters, which is 100 square meters, and therefore is called a weave.

Here are some typical examples of the sizes that a land plot of 15 acres can have:

In the future, if you suddenly forget how to find the area of ​​a rectangular plot of land, remember a very old joke. “Grandfather asks a fifth grader: “How to find Lenin Square?” And he replies: “You need to multiply the width of Lenin by the length of Lenin” :)))
