Hectare to Square Meter (ha to m²)
Result
10,000 Square Meter
Formula
m² = ha × 10,000
1 ha = 10,000 m², and 1 m² = 0.0001 ha.
Area factors are the square of the length factor: 1 ft = 0.3048 m, so 1 ft² = 0.3048² = 0.09290304 m². The acre is 43,560 ft² (4,046.8564224 m²) and the hectare 10,000 m².
Worked examples
- 1 ha × 10,000 = 10,000 m²
- 10 ha × 10,000 = 100,000 m²
- 100 ha × 10,000 = 1,000,000 m²
Common mistakes
- Do not apply a length factor to an area: 100 m² is 1,076.39 ft², not 328 ft² (100 × 3.28).
- A plot described as "20 × 30 ft" is 600 ft²; convert each side to metres first or convert the area afterwards — never just one side.
