How area units relate
Area units are squared length units, so the conversion factor is squared too. One foot is 0.3048 m, so one square foot is 0.3048 × 0.3048 = 0.09290304 m². Multiplying square meters by 3.28 instead of 10.76 is the most common mistake.
- 1 hectare is a square of 100 × 100 m, or 10,000 m².
- 1 acre is 43,560 square feet, or about 4,047 m² and 0.405 hectares.
- 1 square kilometer is 100 hectares.
- 1 square mile is 640 acres, or about 2.59 km².
To find the area of a rectangular room, multiply its length by its width in the same unit, then convert the result.

Where the conversions come up
Property listings are the main reason people land here. An apartment advertised at 85 m² is 915 square feet, and a 1,500 sq ft house is about 139 m², often written m2 on listing sites. Land is sold in acres in the US and UK and in hectares almost everywhere else. Flooring, paint and tiles are priced per square meter or per square foot, so one wrong factor on a floor plan turns into a wrong order.
Shortcuts: square meters to square feet is roughly times 11 (10.76 exactly). An acre is a bit under half a hectare, and a hectare is about two and a half acres. A football pitch is about 0.7 hectares, which helps when you try to picture a plot.
How to use it
- 1Choose the unit from the listing or plan on the left and the one you think in on the right.
- 2Type the area. If you only have length and width, multiply them first in the same unit, then enter the product.
- 3Read the result and the factor, see the same area in acres, hectares and the rest below, and copy the number or a link.
Frequently asked questions
How many square feet are in a square meter?
