The square feet people look up most

400 sq ft = 37.1612 m²: A studio apartment, or about the footprint of a double garage.
1,000 sq ft = 92.903 m²: Divide by 10.76, not 3.28 - area factors are the square of the length factor.
1,500 sq ft = 139.3546 m²: Around the size at which a US listing stops being called a starter home.
2,000 sq ft = 185.8061 m²: Around the median new American home - a size a European agent would advertise in square metres.

How the square feet to square meters calculation works

A square foot is exactly 0.09290304 square meters:

square meters = square feet × 0.09290304

That factor is 0.3048 squared. Area factors are the square of the length factor, which is the mistake people make most often here: dividing floor area by 3.28 rather than by 10.76 leaves you with a figure three times too large.

Property listings are the usual reason to convert:

A 400 sq ft studio → 37.2 m²
A 750 sq ft one-bedroom → 69.7 m²
A 1,200 sq ft apartment → 111.5 m²
A 2,000 sq ft house → 185.8 m² — near the US median new-build
A 3,000 sq ft house → 278.7 m²

For context, the median new British home is about 76 m² (818 sq ft) and the median new American one roughly 200 m² (2,150 sq ft) — a gap that survives every conversion.

What counts as floor area differs by country, which matters more than the arithmetic. US listings usually quote gross living area excluding garages and unfinished basements. Many European measurements are internal floor area excluding walls, and some Asian markets quote a "saleable" area that includes a share of common corridors and lobbies. Two identical buildings can differ 20% on paper before any conversion happens.

The mental shortcut is divide by 10 and add 8%: 1,000 sq ft → 100 → 108 m², against a true 92.9. That one overshoots — better is divide by 10.76, or just take a tenth and subtract 7%.

Frequently asked questions

What is a square in roofing?

A unit of 100 square feet, or 9.29 m², used for estimating and pricing American roofing and flooring. A 2,000 sq ft roof surface is 20 squares, or 185.8 m². The unit exists because a bundle of asphalt shingles covers a third of a square, so an order in squares comes out in whole bundles rather than awkward fractions of one.

How do I convert a room that is not a rectangle?

Split it into rectangles, measure each, add them together and convert once at the end - converting each piece separately and adding rounded figures introduces error for nothing. Where a room has a bay or a chimney breast, measure the overall rectangle and subtract the missing pieces. Then add 5 to 10% for cutting waste before ordering anything.

How do I convert a price per square foot?

Multiply by 10.764, not by 3.28 - a rate per unit area inverts the area factor exactly as the area does. Flooring at $4 a square foot is $43.06 a square metre, which is why an American quote and a European one can look wildly different until the units are matched. Rent, land and labour rates all behave the same way.
