Formula and methodology
Formula: m² = ha×10,000; km² = ha/100; international acres = m²/4046.8564224; ft² = m²×10.7639104167.
A hectare is exactly 10,000 square metres. The acre output uses the international acre, keeping it separate from historical survey-acre conventions.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Hectares — ha; minimum -1000000000; maximum 1000000000
Worked example
| Input | Value |
|---|---|
| Hectares | 2.5 |
2.5 ha = 25,000 m² = 0.25 km² = about 6.17763 international acres.
Assumptions and limits
- The area uses the international hectare and international acre conventions.
- The result is area, so linear conversion factors are squared where appropriate.
- No parcel boundary, title, legal, or country-specific land-record rule is inferred.
