How to Convert Square Foot to Hectare
- 1 ft² = 0.000009290304 ha
- 1 ha = 107639.1042 ft²
- Example: convert 15 ft² to ha: 15 ft² = 15 × 0.000009290304 ha = 0.00013935456 ha
Formula
ha = ft² × 0.000009290304
or ha = ft² ÷ 107639.1041671
Derivation from SI units:
- 1 ft² = (0.3048 m)² = 0.09290304 m²
- 1 ha = 100 m × 100 m = 10 000 m² (a non-SI unit accepted for use with the SI)
- 1 ft² = 0.09290304 m² ÷ 10000 m² per ha = 0.000009290304 ha
Both units are defined exactly, so the factor is exact. Square Foot definition: square foot; Hectare definition: hectare.
Worked examples
- A reading of 5 ft² converts to 0.00004645152 ha.
5 ft² × 0.000009290304 = 0.00004645152 ha - A value of 500 ft² is 0.004645152 ha.
500 ft² × 0.000009290304 = 0.004645152 ha
