Difference between Hectare and Acre

Although both Hectare and Acre are the units for measuring land, plot, etc., they differ from each other slightly. Below we have enlisted five basic differences between the two.

What is Hectare?

Hectare is a measurement system that is used commonly within the aegis of the metric system for land measurement purposes and plots globally. It’s a metric unit for area measurement. Typically, it is represented by the symbol “ha”.

Invented in 1795, this measurement unit is a fusion of two Latin terms, namely Hect and Area.

One hectare is equivalent to 10,000 square meters. However, within the aegis of the British Imperial System, one hectare equals 2.471 acres.

100 ha equals a square kilometer whereas a farm having 200 ha worth of fields is equivalent to 2 square kilometers of total fields within its ambit.

In the shorter term, a hectare is equal to the size of a football field.

Known as one of the commonly used measurement units for land in farming communities, both units (hectare and acre) are used for measuring larger tracts or plots of land.

Hectare is used for measuring land across the entire world and although it is not an SI unit, a hectare is the sole named unit of area which is acceptable for usage in tandem with SI units as well.

It has been classified as such by the International Committee for Weights and Measures.

History of Hectare

In the year 1960, the metric system got updated as the International System (SI) of Units. Hectare didn’t receive international recognition, as the International Committee for Weights and Measures (CIPM) didn’t count hectare as an SI unit. However, the CIPM claimed that hectare will be non-metric and non-SI unit but will be acknowledged and accepted as a usable International System of Units.

In 1972, the ECC (European Economic Community) proceeded with a directive cataloguing replicated counsel of the General Conference on Weights and Measures (CGPM).

What is Acre?

Acre is one of the oldest units for land measurement and is applied globally for measurement of vast land tracts and plots. It has evolved considerably over the years as well. Used conventionally throughout the reign of the British Empire, the Anglo-Saxon acre has been defined as a strip of land which is 1×1/10 furlong or 40×4 rods and 660 x 66 feet overall. Used throughout the U.S. and Imperial systems of measurement alike, the contemporary acre works out to 4,840 square yards and 4,047 square meters along with 0.4047 hectares and 43, 560 square feet. It may also be defined as the area which is a furlong long and four rods wide.

Imperial units are systems for measures and weights which were used officially from the year 1824 in Great Britain till the metric system was adopted from 1965. It is now defined in metric unit terms and the units are also a part of the U.S. Customary System which directly derives from the Imperial System in Britain. Acre comes from aker which is a world in ancient English, indicating open field and it does not have any shape which has been prescribed. The acre is mostly written in its full form and the ac abbreviation is also used in this regard.

Acre is used throughout the globe including several countries like Germany, Canada, Jamaica, Spain, U.S., France and several countries in South Asia like Sri Lanka, Pakistan and Bangladesh apart from India. The unit is used more commonly in the United Kingdom and back in the Middle Ages in England, one acre of land was classified as the area which could be ploughed in a single day by a yoke of oxen or eight oxen. The measurement unit has attained immense popularity over the years throughout the British Empire and farm sizes have also been expressed through the same in spite of square miles making for a more logical option instead.

You should make a note of the fact that acre does not come with any standard measurement and it does not indicate the same area in several countries where it is majorly in usage. An acre in Scotland works out to 1.27 standard acres and the Irish acre is equivalent to 1.6 U.S. or British acres in total. Residential plots are measured on the basis of square feet in India while agricultural land measurement is done through hectares or acres. Bigha is a unit which is used more locally throughout northern parts of India.

History of Acre

The acre is a unit of land measurement in the United States Customary and the British Imperial systems. The world acre is derived from the Latin word “Ager” and the Middle English word “Aker” which means “Field”. The origin of an acre can be defined as the area that can be ploughed with an ox and wooden plough in a single day. 

The Anglo-Saxon acre can be defined as the stripe of land with 1 Chain (66 ft.) and 1 Furlong (660 ft.).

Current Use of Hectare
