How it works
- Enter an area and choose its source unit.
- The value is normalized to square meters.
- All metric, imperial, and land-area results update together.
The conversion method
square meters = input × source factor
result = square meters ÷ target factor
For example, one acre uses the exact factor 4,046.8564224 m²; dividing that value by 10,000 gives about 0.404685642 hectares.
