Convert acre to hectare

What is an acre?

An acre or ac for short is still one of the popular and common metrics in Great Britain and other English-speaking regions of the world. It is utilized in trade and can be used officially, as its correspondence to the standard options is established.

The history of this metric goes back to the Middle Ages. This term was utilized to evaluate the area cultivated by one peasant with one ox per day. Then, the definition was changed a bit and told that one acre corresponds to an area with the sides of 1 chain by 1 furlong or 66 feet by 660 feet.

Only in the middle of the XX century, scientists determined acre as nearly 4046.856 square meters, 0.004 square kilometers, 0.405 ha, or 4840 square yards. Therefore, this option keeps its position on the land market and can be easily recalculated to other units, including those from the unified system.

What is a hectare?

A hectare is utilized to evaluate areas. It was introduced in 1879 together with the parameters and international designation as ha.

The term has a Greek origin and means a hundred ares. The latter is also a metric equal to a square with 10 m sides. Thus, our metric is a hundred ares. To convert hectares to some other option, the following ratios should be utilized:

• the ha size corresponds to hectometer;
• 1 such metric is the same as 100 dam²;
• in square m it is 10,000;
• the same value in square km is 0.01.

This metric is mainly utilized in agriculture and forestry to determine the size of forest plantations, agricultural land, farm fields and other non-residential areas. Also, the maximum size of a rugby field is just over 1 ha and an ordinary football field for international matches occupies an area of 0.7 hectares.
