The formula
To convert square feet to square meters, multiply the area in square feet by 0.09290304:
square meters = square feet × 0.09290304
A worked example
Say you have a 1500 square foot apartment — a typical small US home — and you want that size in square meters:
1500 × 0.09290304 = 139.35456 square meters
So a 1500 square foot place is a little over 139 square meters.
Why the number is exact
Here is the neat part about area: the factor is just the length factor squared. One foot is defined as exactly 0.3048 meters, so a square foot is a square that is 0.3048 meters on each side. Multiply the two sides together — 0.3048 × 0.3048 — and you get 0.09290304 square meters. Because the length definition is exact, squaring it stays exact, which is why this conversion never needs to be rounded at the source.
When you'll use it
Comparing apartment and house listings between the US and the rest of the world, reading architectural plans that mix units, working out flooring or paint quantities, and translating real-estate sizes for an international audience.
