How to use
- Enter the area figure you have (floor plan, land deed, or CAD export).
- Select its unit: ft², m², acres, hectares, etc.
- Choose the unit your audience expects (e.g. m² for EU listings, ft² for US).
- Compare two properties by converting both to the same unit.
- Use for gardening, flooring, paint estimates, or agriculture.
- Round sensibly: property areas are often quoted to one decimal.
Examples
- 2,500 ft² to m² (home size)
- 1 acre to m² (land)
- 100 m² apartment to ft²
- 1 hectare to acres (farm)
- 500 cm² to in² (small surface)
- 0.25 km² to acres (large parcel rough check)
FAQ
- Accuracy?
- Conversions use standard SI definitions and NIST imperial constants.
- Acre vs hectare?
- 1 hectare ≈ 2.471 acres. Both are common in land measurement.
- Why doesn’t ft² match my manual?
- Check whether the source used survey feet or rounded intermediate steps.
- Can I convert linear feet to square feet?
- Not without a width—this tool needs an area input, not length alone.
- Metric vs US survey acre?
- Consumer tools use the international acre unless labeled survey-specific.
- Is data uploaded?
- No. Calculations are local.
