Acres to Hectares Converter

One acre equals exactly 0.404686 hectares. Both units measure land area, but a hectare is a clean metric unit (10,000 square meters), while an acre comes from an older imperial definition (43,560 square feet), which is why the conversion factor isn't a round number.

One hectare equals about 2.471054 acres, the exact reciprocal of the acre-to-hectare factor. A hectare is noticeably larger than an acre, roughly two and a half times the size, so converting from hectares to acres always increases the number.

Acres remain the standard land unit in the United States and, informally, the United Kingdom. Hectares are the standard almost everywhere else, including most of Europe, and in international agriculture, forestry, and land-use statistics. If you're comparing land data from different countries, converting to a common unit first avoids confusion.

Yes, this converter works both directions at once, type a value into the acres field and hectares updates automatically, or type into hectares and acres updates instead. There's no separate "convert" button or direction toggle needed.

It's the same area expressed in square meters, the base metric unit both acres and hectares are ultimately defined against (1 hectare = 10,000 m², 1 acre = 4,046.8564224 m²). It's shown as an extra reference point since square meters are commonly used for smaller plots and building footprints.
