How to use Area Converter
Area units measure two dimensions. The factor between metres and feet is therefore squared when converting square metres and square feet. Acres use international-foot definitions in this calculator.
Regional land units such as bigha can vary by state and locality. They are intentionally absent rather than being assigned one misleading national factor. Verify the local legal definition for land documents.

Questions about this calculation
Why is bigha not available?
Its size varies by locality. One universal conversion would be misleading.
Does doubling a length double its square area?
For similar shapes, doubling both dimensions multiplies the area by four.
