Landarea Measurements - An Overview

The standard unit of land area measurement is the hectare.
Hectare is a metric unit equal to 10,000 square meters or 2.47 acres.
The hectare is the largest unit in this list, followed by the other units of land area measurements such as acre, ground, bigha, square yard, square foot, cent, and square kilometer.
The square mile is the smallest unit in this list.
The hectare and square kilometer are metric units, while the acre, ground, bigha, square yard, and square foot are imperial and U.S. customary units.
It is important to note that some countries and regions may use different units of land area measurement.
For example, acres are still commonly used in the United States and some other English-speaking countries. And bigha is commonly used to measure agricultural land in North India. However, for international communication and comparison, it is generally best to use hectares.
In short, the hectare is the most widely used and accepted unit of land area measurement in the world.

Which Land area measurement is used and where?

Hectares are commonly used to measure large areas of land, such as farms, forests, and national parks.
Acres are commonly used to measure smaller areas of land, such as residential lots, agricultural plots, and golf courses.
Grounds are commonly used to measure agricultural land in South India.
Cents are commonly used to measure small areas of land, such as residential plots and building lots.
Bighas are commonly used to measure agricultural land in North India.
Square feet are commonly used to measure the interior area of buildings and rooms.
Square yards are commonly used to measure the area of patios, decks, and other outdoor spaces.
Square miles are commonly used to measure the area of large geographic regions, such as states and countries.
Square kilometers are commonly used to measure the area of large geographic regions, such as countries and continents.

Frequently Asked Questions on Land Measure Conversion

The measure is in terms of Area (which is length * breadth). Metric system uses Square meter, Square km , Square Mile, Hectare. Imperial System uses Acre, Square Yard, Square Feet and Square Inch.

Hectare is used in Metric system and used to measure very large tracts of land. Mostly agriculture and forest lands mention in terms of hectares. A hectare is 10,000 square meter of land. Acre is used in Imperial system and also used to measure large areas with respect to fields, stadiums , residential and agriculture lands. 1 Hectare is 2.47 times an Acre.

Hectare is bigger than Acre. 1 Hectare (Ha) = 2.47 acres.

A square meter means 1 m x 1 m of area. Square feet is typically used in housing land and room measurements like a 20 x 20 square feet room (400 square feet). Square yard is also used in housing land area measurements and used in countries following Imperial system like US. A square yard is 9 square feet. Square miles / Square kilometers is used for larger areas like river / lake or forest area. For eg, the great bear lake is 31000 sq km / 12000 sq miles in area. Forest covers are also mentioned in sq km like 700,000 Sq km (70 million hectares). The area of ocean, area of earth etc.. are in millions of sq kms or millions of sq miles.

1 Square meter is bigger than square yard and Square feet. 1 Sq meter = 10.76 sq feet and 1.2 sq yard. sq yard is bigger than sq feet and 1 sq yard = 9 square feet. Square miles is the biggest. 1 square mile = 2.59 square kilometers

A plot is a easy way to mark and sell blocks of land. A plot size itself can vary. A 9600 sq feet of land (4 grounds) and if plot sizes are 30x40, then there be 8 plots. If plot size is made as 60x40, then it will have 4 plots.

1 acre is 43560 square feet. If a plot is 7200 sq feet, then 6 plots make an acre.

It is 2400 square feet. 1/2 ground is 1200 Square feet. It is used in land specification for residential houses.

The units are measured in millions of sq km or sq miles. The largest total area in million sq kms are Russia - 17 . Canada - 10 . China - 9.5 . US - 9.3 . Brazil - 8.5 . Australia - 7.7 . India - 3.3 .

Pacific Ocean - 155 million sq kms (60 million sq miles). Atlantic Ocean - 106.5 million sq kms (41 million sq miles). Indian Ocean - 70.5 million sq kms (27 million sq miles).

Sahara desert is 9.2 million sq kms (3.55 million sq miles). Deserts make up 1/3rd of land surface area, which is around 47 million sq kms (18 million square miles).

It is measured in sq kms or sq miles (millions of sq km / sq miles). It is about 510 million square km (197 million square miles). 29% is land area- 148 million sq km (57 million sq miles). 71% is sea area - 362 million sq km (148 million sq miles).
