Convert Acre to Hectare
Units of measurements are used to measure any physical quantity. Sometimes, the unit is preferred to be different according to the situation or place. For instance, in the UK, weight is measured in pounds, while in India, it is measured in Kg. Therefore, it is best to learn how to convert one unit into another of the physical quantity. Not all conversions are to be learned or remembered, hence, some important ones are learned and kept in mind.
Acre to Hectare
Acre is used to defining a piece of land of any shape. It is the unit of land area. An acre is a system of units commonly used in the United States and its territories. In India, agricultural land is measured both in acres and hectares. The symbol of Acre is ‘ac’ and the symbol of hectares is ‘ha.’
Hectare is not an SI unit but is used with various SI units to measure the area of the land. A SI unit is listed in the International System of Units and accepted worldwide. The land used for measurement can be forest land, agriculture land, land ownership, etc.
For example, A liter is the unit to measure the weight of liquids. Similarly, Acre is the unit to measure the land.
Conversion of Acre to Hectare
To convert acres to hectares, we only need to multiply the numbered value of acres by 0.404686. It is because 1 Acre = 0.404686 Hectares. For example, To convert 20 ac into ha, multiply 20 with 0.404686.
Hectares = 20 × 0.404686
Hectares = 8.09371
1 Acre = 4046.86 square meter ⇢ (1)
1 Hectare = 10000 square meter
1 square meter = 1/10000 Hectare
Substituting the value of square meter in equation (1),
1 Acre = 4046.86 × 1/10000 Hectare
1 Acre = 4046.86/10000 Hectares
1 Acre = 0.404686 Hectares
1 Hectare = 1/0.404686 Acres
1 Hectare = 2.471 Acres
Hence, proved that 1 Acres is equal to 0.404686 Hectares or 1 Hectare is equal to 2.471 Acres.
Let’s consider some quick conversions of acres to hectares, which are listed in the below table:
S.No | Acre | Conversion | Hectares |
1 | 0.5 | 0.5 × 0.404686 | 0.202343 |
2 | 0.4 | 0.4 × 0.404686 | 0.161874 |
3 | 0.2 | 0.2 × 0.404686 | 0.0809371 |
4 | 5 | 5 × 0.404686 | 2.02343 |
5 | 4 | 4 × 0.404686 | 1.61874 |
6 | 2 | 2 × 0.404686 | 0.809371 |
7 | 10 | 10 × 0.404686 | 4.04686 |
Some other conversions
- Hectare to square meter
A Hectare is equal to the area of a square of side 100m.
Area of square = (side)2
If side of a square is 100m
Area of square = 100 x 100
Area of square = 10,000 m2
1 Hectare = Area of square = 10,000 m2
- Hectare to Square Kilometer
Convert hectare to kilometer using the same formula.
1 Hectare = 10,000 m2 ⇢ (1)
1 kilometer = 1000m
1m = 1/1000 km
1m2= 1/(1000 x 1000)
1m2= 1/106 km2
Substituting the value of one square meter in equation (1),
1 Hectare = 10,000 x 1/106 km2
1 Hectare = 10,000/106 km2
1 Hectare = 0.01 km2
Or
1 km2 = 1/0.01 ha
1 km2 = 100 ha
Hence proved, that one hectare is equal to 0.01 square kilometer and one square kilometer is equal to 100 Hectares. Similarly, one can easily convert it to various units.
