What is a unit of area?

An area unit is a unit of measurement used to determine the size or area of a given flat surface. This means that a unit of area can be used to measure the size of a surface or area such as a field, plot, room, continent and so on.

In the metric system, the most commonly used unit of area is the square metre (m²). This is the area of a square with a side length of one metre. However, other units of area such as the square centimetre (cm²), square kilometre (km²) or hectare (ha) may also be used, depending on the context and application.

Other measurement systems use different units of area. For example, in the Imperial system the basic unit is the square foot (square ft²) and in the British system the acre (acre).

Depending on the context and measurement needs, it is important to use the appropriate units of area.

Different units of area

The most obvious unit of area is the square metre [m²]. However, there are others that are commonly used, for example, in agriculture, forestry and surveying. These include

Hectare - denoted by the symbol ha. 1 ha = 10000 m² The name comes from the prefix hekto- meaning 100 and the name of the unit of measurement ar.
ar - is denoted by the symbol a. 1 a = 100 m². The name is derived from the French are from the Latin area, meaning square; threshing floor; playing field.
Acre - a unit of land area, the name of which comes from acre and is used in Anglo-Saxon countries. 1 acre = 4046.8564224 m².
