Convert between square metres, square feet, acres and hectares. Free, exact, and it works without an internet connection.
Every unit in this converter carries one number, its size in square meters. The square meter is the base, and its own number is 1. A hectare is 10,000. A square foot is 0.09290304.
A conversion is two steps. The tool multiplies your value by the number of the unit you entered, which gives the area in square meters. It then divides by the number of the unit you asked for.
result = value * fromFactor / toFactor
Both fields accept a number. Type into the second field and the first one follows, so a conversion runs in either direction.
Nine units are available: square meter, square kilometer, square centimeter, square millimeter, hectare, acre, square foot, square yard and square mile. Each one also answers to a short form, so a search for sq ft finds the square foot and a search for m2 finds the square meter.
A result is rounded to 12 significant digits. The whole conversion runs in your browser.

The acre and the square foot are exact numbers here, not measurements. An acre is defined as 4,840 square yards, and the yard has been exactly 0.9144 meters since the international yard and pound agreement of 1959. Square that yard and multiply by 4,840, and the acre comes out at 4046.8564224 square meters with no rounding anywhere.
Common area conversions:
The hectare is not an SI unit, but the same bodies that define SI accept it for land. The square kilometer is the SI form, and 1 square kilometer is 100 hectares.
The nine converters share one workspace, so a value typed here is still in the field when you open another measurement. For the side of a plot rather than its area, use the Length Converter. For the space inside a container, use the Volume Converter.
