How do I convert square feet to square metres?

Multiply the square feet by 0.09290304. The exact relationship is 1 ft² = 0.09290304 m², so for example 1 ft² equals about 0.092903 m².

How many m² are in one ft²?

There are 0.092903 square metres in one square foot (1 ft² = 0.092903 m²).

How do I convert square metres back to square feet?

Divide the square metres by 0.09290304, or equivalently multiply by 10.7639. The converter does this automatically when you type into the Square Metres field.

Where does the factor 0.09290304 come from?

One foot is exactly 0.3048 metres, and area scales with the square of length, so 0.3048² = 0.09290304 — the exact square-foot to square-metre factor.

How many square feet are in a square metre?

About 10.764 square feet make up one square metre (1 m² = 1 ÷ 0.09290304 ≈ 10.7639 ft²).

Square Feet to Square Metres Converter

This area converter turns square feet (ft²) into square metres (m²) and back, useful for property listings, floor plans, and comparing US/UK and metric measurements. Type into either field and the other updates live.

How it works

The conversion is a single multiplication by an exact factor:

m² = ft² × 0.09290304 and ft² = m² ÷ 0.09290304

That factor is not arbitrary — one foot equals exactly 0.3048 metres, and because area is length squared, the square-foot factor is 0.3048² = 0.09290304. The inverse direction is the same factor divided out, which is approximately × 10.7639.

Example

Convert a 500 ft² apartment:

500 × 0.09290304 = 46.45 m²

Going the other way, a 75 m² flat is 75 ÷ 0.09290304 ≈ 807.3 ft².

Square Feet (ft²)	Square Metres (m²)
1 ft²	0.092903 m²
10 ft²	0.92903 m²
100 ft²	9.2903 m²
500 ft²	46.4515 m²
1000 ft²	92.903 m²
