How to Convert Square Feet to Square Meters
Why area conversions use squared factors, with worked examples.
Published by QuickUtilaUpdated 2 min read
Floor plans, property listings and flooring products switch between square feet and square meters depending on the country. Converting correctly is easy once you know why area conversions behave differently from length conversions.
The exact conversion factor
Why the factor is squared
A foot is 0.3048 meters. A square foot is a square measuring one foot on each side, so its area is 0.3048 m × 0.3048 m = 0.09290304 m². Because area has two dimensions, the length factor is multiplied by itself.
The most common mistake is to multiply square feet by 0.3048 — the length factor — which gives an answer more than three times too large.
Worked examples
- 11,200 × 0.09290304 = 111.483648
Therefore: 1,200 square feet is about 111.48 m².
- 125 ÷ 0.09290304 = 269.097…
Therefore: 25 square meters is about 269.1 ft².
Converting room dimensions
If you have a room’s length and width, either convert both lengths first and then multiply, or multiply first and convert the area. A 12 ft × 15 ft room is 180 ft², which is 16.72 m². Converting the sides first gives 3.6576 m × 4.572 m = 16.72 m² — the same answer.
