What this converter does: it turns an area in square feet into the same area in square metres, so a listing quoted in sq ft can be compared directly with European listings quoted in m². If your starting figure is already in square metres, use the Free Square Metres to Square Feet Converter instead. Once you know the size in m², our Free House Buying Costs Calculator for Europe helps you work out what buying that home would cost overall.

How to use the converter

1. Type the area in the square-feet box — the square-metre value updates as you type, with no button to press.
2. Read the result line: the converted area, plus both directions of the rate (1 sq ft in m², and 1 m² in sq ft).
3. To go the other way, type in the square-metres box instead, or press Swap direction to flip the converter and carry the converted value over as the new input.
4. Decimals are welcome: 850.5 sq ft converts just as easily as 850 sq ft.
5. Check what the listing measures: floor areas can be quoted as living area, gross internal area or total plot area — compare like with like.

The formula

Let A_ft be the area in square feet and A_m be the same area in square metres. The two directions are:

• Square metres from square feet: A_m = A_ft × 0.09290304
• Square feet from square metres: A_ft = A_m × 10.7639104 (equivalently, A_m ÷ 0.09290304)

The number 0.09290304 is exact, not rounded: the foot is defined as exactly 0.3048 m, so one square foot is 0.3048 m × 0.3048 m = 0.09290304 m². Any rounding you see comes only from how many decimal places are displayed. For the reverse direction in its own tool, see the Free Square Metres to Square Feet Converter.

Worked example

A flat is listed as 750 sq ft, and you want to compare it with European listings priced per square metre:

• Multiply by the exact factor: 750 × 0.09290304 = 69.67728 m² (shown as 69.6773 m²)
• Check the other way: 69.67728 ÷ 0.09290304 = 750 sq ft, back where we started
• Illustrative price check (hypothetical numbers only, not a market rate): at an assumed €4,000 per m², the flat would cost 69.67728 × €4,000 = €278,709.12

So the flat is just under 70 m². Try 750 in the converter above to see the same answer, then run the price through our Free Mortgage Affordability Calculator for Expats in Europe to see what kind of loan that figure implies.

Square feet to square metres conversion table

Square metres are shown to four decimal places. The underlying factor is exact, so the only rounding is in the display.

Everyday benchmarks: sizes that build a feel for the units

The sizes below are round examples to build a feel for the two units — not statistics about any city’s homes. Each line is a straight conversion of the same area:

• A 10 ft × 10 ft room — 100 sq ft = 9.2903 m². Multiply the sides to get square feet, then convert the area.
• A compact flat example — 500 sq ft = 46.4515 m². A figure you may see on a one-bedroom listing.
• A mid-size flat example — 750 sq ft = 69.6773 m². Just under 70 m².
• A larger flat example — 1,000 sq ft = 92.903 m². The converter’s default value.
• A family house example — 1,500 sq ft = 139.3546 m². One and a half times the default, in either unit.
• One square metre in reverse — 1 m² = 10.7639 sq ft. A square metre is a square roughly 3.28 ft on each side.

For land rather than floor area, the Free Acres to Hectares Converter and Free Hectares to Acres Converter cover plots and fields.

Rounding and exactness

The factor 0.09290304 is exact, so this converter never estimates: the only rounding is the four decimal places shown on screen. For money sums, convert first with the full result and round the euros last — rounding the area to whole square metres before multiplying by a price per m² can move the total by thousands. And remember that a listing area figure depends on what the seller measured: living area, gross internal area and plot area are different numbers, so confirm which one a listing quotes before comparing prices.
