How this conversion works

Apartments, rooms, flooring and garden plots are listed in square feet in the US and square metres almost everywhere else. Type either side — a 650 sq ft one-bedroom is 60.39 m²; a 75 m² flat is 807.29 sq ft.

The common error is converting area with the length factor: multiplying square feet by 0.3048 instead of 0.09290304 overstates the metres more than threefold. Whenever the unit has a 'square' in it, the factor must be squared too — the table below is built on the squared factor throughout.

The exact formula

square metres = square feet × 0.09290304
0.09290304 is 0.3048² — area factors are length factors squared, which is why the number looks so much smaller than the length conversion. The reverse is square feet = square metres ÷ 0.09290304 (1 m² = 10.7639 sq ft).

Exact constants, honest rounding. Every conversion here uses the exact international definitions printed on the page (1 inch = 2.54 cm exactly, 1 lb = 0.45359237 kg exactly). Results are rounded for display only — the working underneath is never rounded. For engineering, medical or legal work, verify against a certified instrument.
