Area Converter
Convert square feet to square meters, acres to hectares, and every other area unit instantly.
This area converter changes any surface measurement into another unit the moment you type. It focuses on the conversions used in property, construction and land — square feet to square metres for floor plans, and acres to hectares for land — and does one job only: area, with nothing else mixed in.
About the area converter
Area measures the size of a two-dimensional surface, such as a floor, a wall or a plot of land. It is expressed in squared length units: square metres (m²) and square kilometres in the metric system, square feet (ft²), square yards and square miles in the imperial system, plus the acre and the hectare for land. Real-estate listings, flooring quotes and land records routinely switch between these, making conversion a common task.
All values are anchored to the square metre, the SI unit of area. Because area scales with the square of length, the factors are the length factors squared: one square foot is 0.3048² = 0.09290304 m², and one square mile is 1609.344² ≈ 2,589,988 m². An acre is defined as 4,046.8564224 m² and a hectare as exactly 10,000 m² (100 m × 100 m), so 1 hectare ≈ 2.471 acres.

Frequently asked questions
How do I convert square feet to square meters?
Multiply square feet by 0.092903. For example, 1,000 ft² × 0.092903 ≈ 92.9 m². To convert square metres to square feet, multiply by 10.7639.
How many square feet are in an acre?
One acre is exactly 43,560 square feet, or about 4,046.86 square metres. It is a standard unit for land area in the US and UK.
How do I convert acres to hectares?
Multiply acres by 0.404686 to get hectares, since one hectare equals about 2.471 acres. So 10 acres ≈ 4.05 hectares.
What is the difference between a hectare and an acre?
A hectare is a metric land unit equal to 10,000 m² (a 100 m × 100 m square). An acre is an imperial unit of 4,046.86 m². One hectare is roughly 2.47 acres.
Why do area factors look like length factors squared?
Because area is length × length. If 1 foot = 0.3048 m, then 1 square foot = 0.3048² = 0.09290304 m². That is why converting area uses the square of the length conversion factor.
