Acres to Hectares

Formula

An international acre is 43,560 square feet, which is 0.40468564224 hectares:

hectares = acres × 0.40468564224

A hectare is 10,000 square meters. The square-meter pages convert a measured area, not a land parcel named in acres.

Assumptions

• The value can be zero and cannot be negative.
• The result is shown with up to six decimal places.

Worked example

1 acre equals 0.404686 hectares.

Input definitions

Acres

International acres based on the international foot.

Limitations

Some older surveys used a slightly different acre. This page uses the international acre.
