UAE is a diverse country, and different land measurement units are used in different parts of the country, the land size is calculated and written in only standard units of measurement. Some of commonly used measurement units are acre, hectare, square foot, square meter, etc. For instance, a hectare is a common metric system unit particularly used to measure large land plots and farmlands. After elucidating both units, this article will explain the Hectare To Acre (Ha To Ac) formula and conversion for further clarity.

About Hectare (ha)

Hectare is a non-SI metric unit of area that equals 10,000 square metres or 2.471 acres. Simply put, a hectare is approximately the size of a football field. The term is commonly represented by the symbol ‘ha.’ A hectare is also used to describe the area of a square-shaped land that has sides of 100 meters. It is commonly used to measure vast agricultural lands, as well as for land sale, land planning, land deeds, management, town planning, and forestry. Although a hectare is a non-SI metric unit (International System of Units), it is the only measurement unit of area accepted with SI units.

  • The History of Hectare

The term ‘hectare’ is derived from the Latin word area and the Greek word hect, meaning hundred. It is a customary measuring unit in the United States and Britain and was first used in 1795 when the metric system was introduced. The metric unit of a hectare is commonly used in the European Union, the United Kingdom, Canada, and Myanmar. In 1960, the metric system was updated. Although a hectare was declared a non-metric and non-SI unit by the International Committee for Weights and Measures (CIPM), it was acknowledged in the International System of Units.

  • Dimensions of Hectare

While calculating 1 hc to ac, you can consider the following conversion formula- one hectare is about 2.47 acres, and an acre is about 0.4047 hectares. One hectare is equivalent to 10,000 square meters. However, per the British Imperial System, one hectare equals 2.471 acres. Additionally, 100 hectares equals a square kilometre, whereas 200 hectares equals 2 square kilometres.

About Acre (ac)

Like a hectare, an acre is also a unit of land measurement in the customary United States and British Imperial Systems. It is used to measure a land of any shape, including circles, rectangles, or even hexagons. The word acre is derived from Old English aker, similar to ager from Latin, meaning field. One acre equals 0.4047 hectares or 4047 square meters and is denoted by ‘ac.’

  • The History of Acre

In the late 1200s, the term acre was first implemented by the English Monarchy for the use of land measurements. Later, in 1878, the British Weights and Measures Act defined 1 hectare as 4840 square yards. Before the metric system was introduced, the standard measurement of an acre was different among various European countries. Today, however, it is part of the US customary and imperial units of measurement.

  • Dimensions of Acre

An acre is equivalent to 43560 square feet and measures about 40% of a hectare, i.e. about 4047 square meters or 1/640 of a square mile. The area of an acre is one chain, i.e. 66 feet by 1 furlong, i.e. 660 feet. One acre is the approximate size of 16 tennis courts, or close to the size of a football field (as the average football field is believed to be approximately 1.86 acres).
