What is Hectare?

A hectare refers to an area of a square comprising 10,000 units of square meters, with each side measuring 100 metres. Also, 1 square kilometre contains 100 hectares. Hectare is primarily used to measure land.

An international rugby union field comprises an area of almost 1 hectare (1.008 hectares), with the size of an average American baseball field measuring 1 hectare.

Although a non-SI metric unit, a hectare is the only unit for measurement of area accepted for use with SI units.

The term ‘hectare’ was first coined with the introduction of the metric system in 1795, and is a portmanteau of ‘hecto’ and ‘are’. ‘Hecto’ denotes a factor of one in the metric system, whereas ‘are’ refers to an area of measurement equalling 100 square metres.

The use of ‘are’ was excluded with an introduction of the International System of Units (SI) in 1960. However, hectare continues to remain a valid unit of area measurement.

Hectare also has its origin in the Greek word “hekaton”, meaning 100.

What is an Acre?

An acre is equal to 43,560 square feet precisely. It measures close to 40% of a hectare, i.e. 4,047 square meters, or 1/640 of a square mile.

The traditional definition of an acre is the area of 1 chain (66 feet) by 1 furlong (660 feet), which equals 10 square chains. 1 acre equals approximately 16 tennis courts, around 60% of a football field, or 150 cars parked in a square formation.

The English monarchy implemented the use of acre for area measurement in the late 1200s. In 1878, 1 hectare was defined as 4,840 square yards by the British Weights and Measures Act.

Also, the official measurement of an acre differed among European countries before the introduction of the metric system. At present, it is part of the US customary and imperial units system of measurement. In India, an acre is primarily used to measure agricultural land.
