Area Converter
Square units, acres and hectares.
1 square inch = 0.000000064516 ha. Enter any value to convert square inches (in²) to hectares (ha), or use the table below for common values.
ha = in² × 0.000000064516
Example: 10 in² = 0.00000064516 ha. To convert the other way, use in² = ha × 15,500,031.
Quick mental estimate: multiply by about 0.000000065.

The square inch is the area of a square with 1-inch sides, exactly 6.4516 cm². It is used for small surfaces and, in psi, for pressure.
The hectare is 10,000 m² (100 m × 100 m), the standard unit for farmland and forests in metric countries.
Use the formula ha = in² × 0.000000064516. For example, 10 in² = 0.00000064516 ha.
1 in² = 0.000000064516 ha.
Use in² = ha × 15,500,031. 1 ha = 15,500,031 in².
