How it works

Every unit converts to square meters first using exact definitions — 1 ft² = 0.09290304 m² and 1 yd² = 0.83612736 m² (both derived from the exact meter definitions 1 ft = 0.3048 m and 1 yd = 0.9144 m), 1 hectare = 10,000 m², and 1 international acre = 4,046.8564224 m² exactly — then from square meters to the target unit.

Converting through a common base unit keeps every conversion pair exact, the same approach this site's other unit converters (length, weight, pressure) use.

FAQ

Why is an acre such an unusual-looking number of square meters?

An acre originated as the area a team of oxen could plow in a day, historically defined as 1 chain by 1 furlong. It was later standardized to exactly 4,046.8564224 m² so it converts cleanly to other units, but the number itself still reflects that older, non-metric origin rather than a round figure.

What's the difference between a hectare and an acre?

A hectare (10,000 m², about 2.47 acres) is the standard metric unit for land area, while an acre (about 4,047 m²) is the traditional unit still used for real estate and farmland in the US and a few other countries. Neither is 'more correct' — they're just different regional conventions for the same kind of measurement.
