What Is Hectare?

Hectare (symbol: ha) is a unit of area equal to 10,000 square meters. It is not an S.I. unit, but it is accepted in the S.I. system.

1 hectare $= 2.471$ acres $= 10,000$ square meters

It is commonly used to measure land area in forestry, agriculture, and land management. Hectare is a convenient unit for expressing huge land areas and is frequently used in estimates for crop yields, land use planning, and environmental impact assessments.

What Is Acre?

An acre (symbol: ac) is a unit of land area in the imperial and US customary systems of measurement that is equal to 43,560 square feet or approximately 4046.86 square meters. 

1 acre $= 0.405$ hectares $= 4046.86$ square meters $= 43,560$ square feet

Currently, the acre is employed as a unit for measuring large plots of land, such as real estate, agricultural land, and natural resource management. Also, the unit acre is normally used to plan and expand urban areas.

Hectare to Acre Conversion Formula

It is important to know what 1 hectare to acre actually means. We must also know what is a conversion factor. The conversion factor of a hectare to acre can be written as:

1 hectare $= 2.47105$ acres

So, to do hectare to acre conversion, you may use the following hectare to acre formula:

  Hectare to Acre Formula
  Acres $= \text{Hectares}\times 2.47105$

Similarly, in the conversion of acres to hectares, we have 

1 acre $= \frac{1}{2.47105}$ hectares $= 0.404686$ hectares

    Acre to Hectare Formula
    $\text{Hectares} = \frac{Acres}{2.47105}$

How to Convert Hectare into Acre: Steps

Steps to convert hectare to acre are as follows:

Step 1: Write down the hectare value that needs to be converted to acres.

Step 2: Multiply the hectare value by the conversion factor, i.e., 2.47105, to obtain the equivalent value in acres.

Example 1:  10 hectares $= 10 \times 2.47105 = 24.7105$ acres

So, 10 hectares equals 24.7105 acres.

Example 2: If a portion of land measures 5 hectares in area, what will be the equivalent area in acres?

Acres $= \text{Hectares}\times 2.47105$

5 Acres $= (5 \times 2.47105)$ hectares

5 Acres $= 12.35525$ acres

  • Steps to convert acre to hectare are as follows:

Step 1: Write down the acre value that needs to be converted to hectares.

Step 2: Divide the acre value by the conversion factor, i.e., 2.47105, to acquire the equivalent value in hectares.

Example: Convert 50 acres to hectares.

Hectares $= \frac{Acres}{2.47105}$

50 acres $= \frac{50}{2.47105}$

50 acres $= 20.234$ hectares

So, 50 acres is equal to 20.234 hectares.
