How it works
Every area is converted to square metres with a fixed factor, then divided by the target unit’s square-metres-per-unit factor. For example, the implementation uses 1 ft² = 0.09290304 m², 1 acre = 4,046.8564224 m² and 1 hectare = 10,000 m².
Assumptions & limits
- Uses defined square-unit conversion factors; results are as precise as the input values.
- Converts area only; it does not infer area from lengths or account for an object’s shape.

FAQ
