Area Converter

An acre is a unit of area commonly used for land. 1 acre = 43,560 square feet ≈ 4,046.86 m² ≈ 0.4047 hectares. Historically it was the area a yoke of oxen could plow in a day. A standard American football field is about 1.32 acres.

A hectare is the metric unit for large areas, especially farmland. 1 hectare = 10,000 m² = 100 m × 100 m = 2.471 acres. The hectare is the metric counterpart to the acre and is used in most countries outside the US.

Area is measured in squared units (sq m, sq ft, etc.) because it covers two dimensions. A meter measures length; a square meter measures the area of a 1m × 1m square. Doubling the side of a square quadruples its area, not doubles it.

Because the conversion factor is squared. 1 ft = 0.3048 m, so 1 ft² = (0.3048)² m² = 0.0929 m². Squared units use squared conversion factors. The calculator handles this automatically.

Large areas: cities, counties, states, countries, lakes. 1 mi² ≈ 2.59 km². New York City is about 302 mi² (783 km²). Useful for geography, real estate at scale, and environmental data.

No, this is a unit converter. For area from length × width (rectangles, square footage of rooms), use the square footage calculator or the area calculator hub for other shapes.
