What Is Acres to Hectares Converter?
This converter changes land area from acres to hectares, the standard metric unit used in agriculture and real estate around the world. One hectare is exactly 10,000 square meters, or the area of a 100-by-100 meter square.
Because an acre equals about 4,046.86 square meters, it is roughly 0.4047 hectares. Practically, 1 hectare is about 2.471 acres, and each acre is a little under half a hectare. The calculator also gives the equivalent in square meters for precise planning work.
Formula
1 acre = 4,046.8564224 m²
1 hectare = 10,000 m²
Hectares = acres × 4,046.8564224 / 10,000
= acres × 0.40468564224
Applications
- Converting farm sizes when buying or leasing land internationally
- Comparing US acre listings with metric hectare-based records
- Scaling crop-yield and input rates that are quoted per hectare
- Reporting conservation easements and land-use statistics in metric units
