Area converters
Area units split along the same metric/imperial line as length, but the conversion factors are squared — which is why a quick mental estimate that works for feet-to-meters goes badly wrong for square feet to square meters. Land measurement adds its own units: the acre (imperial, still standard for US and UK property) and the hectare (metric, standard almost everywhere else). All factors here derive from the exact 1959 international yard and pound agreement definitions.

Area units in terms of the square meter
Every area unit on Convertitive is defined as an exact ratio of the square meter (m²), the reference unit for this category. The table below shows what one of each unit equals in square meters — the constant every converter on this page is built from.
| Unit | Symbol | 1 unit in square meters |
|---|---|---|
| Square meters | m² | base unit |
| Square feet | ft² | 0.092903 m² |
| Acres | ac | 4046.86 m² |
| Hectares | ha | 10000 m² |
| Square kilometers | km² | 1000000 m² |
| Square miles | mi² | 2589988 m² |
| Square centimeters | cm² | 0.0001 m² |
| Square inches | in² | 0.00064516 m² |
| Square yards | yd² | 0.836127 m² |
| Square millimeters | mm² | 1.0000 × 10^−6 m² |
To convert between any two units, Convertitive scales the input to square meters using these factors and then back out to the target unit — so every result on this page traces to a single, exact definition rather than a chained approximation.
