Acres to Hectares Converter

One acre is 0.40468564224 hectares, a little over two fifths of a hectare. So about 2.47 acres fill one hectare, and 10 acres is about 4.05 hectares.

To convert acres to hectares, multiply by 0.40468564224. For example, 5 acres equals exactly 2.0234282112 hectares.

To go from hectares back to acres, divide by 0.40468564224. For example, 10 hectares is about 24.710538 acres.

Common values in acres converted to hectares, rounded to 6 decimal places.

The acre had two slightly different sizes in the US until the end of 2022. The international acre is built on the foot of exactly 0.3048 meters. The older U.S. survey acre was built on the survey foot, 1,200/3,937 meters, and was about 4,046.8726 square meters, roughly two parts per million larger. NIST says the survey foot should be avoided from January 1, 2023, except for historic and legacy records, and this converter uses the international acre.

The difference is tiny: on 1,000 acres it is about 0.00161875 hectares, a little over 16 square meters. It only matters when matching old survey records to the last digit.

Converting Per-Acre Rates

A rate per acre, such as a yield or a price, goes the other way: a hectare holds about 2.4711 acres, so multiply a per-acre figure by about 2.4711 to get the per-hectare figure. The Crop Yield per Acre Calculator works per acre, and the Price per Acre Calculator turns a sale price into a price per acre.
