# Hectare

A hectare (ha) is a metric measurement of area equal to 10,000 square meters or 2.47105 acres.

## What is a hectare

A hectare is a measurement of area in the metric system of measurement. The name "hectare" is derived from the metric unit of area, "are," (1 are = 100 m2) and the metric prefix "hecto-" which denotes a factor of 100. Thus, 1 hectare = 100 ares = 10,000 m2. The figure below is a hectare example depicted as a 100 x 100 meter square area.

Although the hectare is a metric unit, it is not an SI (International System of Units) unit. It is, however, accepted for use within SI, and 1 hectare is the equivalent of 1 square hectometre. A hectare is mainly used when measuring large tracts of land between the size of a square meter and square kilometer. Although the are is the primary metric unit of land measurement, the hectare is more commonly used. It is the legal unit of measure in many parts of the world for purposes such as land ownership, agriculture, forestry, and more. The countries in which the hectare is most commonly used include Australia, the US, the UK, Burma, Canada, the EU, and India.

## How large is a hectare

To visualize how large a hectare is, we can compare it to the sizes of various fields used in sports. For example, an American football field is a little over half a hectare, a football field is almost ¾ of a hectare, and an international rugby field is the closest in size to an actual hectare.

• American football field - 6396 yd2 ≈ 0.535 ha ≈ 5347.871 m2

• Football (soccer) field - 7292.5 yd2 ≈ 0.73 ha

• Major league baseball field - 0.83 - 1.12 ha

• International rugby field - 10080 m2 = 1.008 ha

From these examples, we can see that most fields used in sports are relatively close in size to a hectare, giving us some concept of how large an area a hectare is. Another example of an area that is close in size to a hectare is Trafalgar Square, which measures approximately 1.2 ha.
