Square feet to square meters converter

How to convert square feet to square meters

Multiply square feet by 0.09290304: m² = ft² × 0.09290304. The factor is exact, because a foot is defined as exactly 0.3048 m (NIST SP 811, Appendix B), so 1,000 sq ft = 92.90304 m² and a 1,500 sq ft home is 139.35 m². Use it for floor areas; a single length in feet converts with 0.3048 instead.

Why the factor is 0.3048 squared

Square feet (ft²) measure a surface, so the length factor applies twice: 0.3048 m × 0.3048 m = 0.09290304 m².

Multiplying an area by 0.3048 alone makes it 3.28 times too large: 1,000 sq ft would come out as 304.8 m² instead of 92.9 m².

The last row is one acre: 43,560 sq ft, or 4,046.86 m².

Converting a room or floor plan

Multiply length by width in feet, then convert the total. A 12 ft × 15 ft bedroom is 180 sq ft, or 16.72 m². Converting each side first gives the same answer: 3.6576 m × 4.572 m = 16.72 m².

For an L-shaped or irregular plan, split it into rectangles, add their areas in square feet and convert the sum once. The shape area calculator covers 15 shapes, from triangles to circles.

Quick estimate

Dividing by 10 is a common shortcut, but it overstates the metric area by 7.6%: 1,000 sq ft becomes 100 m² instead of 92.9 m². Dividing by 10.76 lands within 0.04%.

Prices per square foot

A price per area converts the opposite way. $200 per sq ft is $2,152.78 per m²: multiply by 10.7639, because a square meter holds 10.76 square feet.

What a listing's figure includes

Converting keeps whatever the original number measured. One listing may count gross area including walls, another only usable floor space, so check that two homes use the same basis before comparing their converted areas.
