About the Acre to Hectare Converter
The acre and the hectare are the two units you'll meet most in Indian agriculture. Farmers and land records in most states talk in acres, while government schemes, research papers and many fertilizer recommendations use hectares. Converting between them correctly avoids costly mistakes – a dose "per hectare" applied "per acre" is almost two and a half times too much.
An acre is an old English unit, defined today as exactly 4,046.8564224 square metres (43,560 square feet). A hectare is a metric unit: 100 m × 100 m, or 10,000 square metres. So:
1 acre = 0.40468564 hectare

Worked example
A farmer has 5 acres. In hectares that is 5 × 0.404686 = 2.0234 hectares. A scheme that supports farmers "up to 2 hectares" would therefore not include the whole 5 acres – worth checking before you apply.
Things to keep in mind
- This conversion is exact – acres and hectares are fixed units everywhere.
- Regional units like bigha, however, are not fixed. Use the Bigha to Acre converter for those.
