Which units can I convert?

Length (m, km, ft, in, mi), weight (kg, g, lb, oz), temperature (°C, °F, K) and area (sq ft, sq m, acre), with more categories added over time.

How do I convert sq ft to sq metre?

Select the Area category, choose square feet as the input and square metres as the output, then type your value for an instant result.

Is temperature handled correctly?

Yes. Temperature uses the correct non-linear formulas (for example °C to °F is (°C × 9/5) + 32), not a simple ratio.
