Square Meters to Square Feet Converter

Apartment listings, flooring and paint estimates use square meters in most countries and square feet in the United States. Area scales with the square of length, so one square meter is about 10.764 square feet, not 3.281. Mixing the two up is a common source of costly estimating mistakes.

1. 1

   Enter a value

   Type a number into the From box. It starts at 1 so you can see the basic ratio straight away. Thousands separators such as 1,250.5 are accepted.

2. 2

   Choose your units

   This page opens with its own units selected. Use either dropdown to pick any other unit in the category, or tap a unit in the all-units list to make it the target.

Tips

• 1 ft² is exactly 0.09290304 m², from (0.3048 m)².
• Rough mental conversion: multiply by 10 and add about 8%.

• Square units scale by the square of the length factor, so length ratios cannot be reused.
• The acre is the international acre. Regional land units such as marla, kanal and bigha are not supported.
• Results show up to 6 decimal places. Values are not rounded during calculation, and a non-zero result that would display as 0 is shown in scientific notation.
