Square Meters Calculator

A square meters calculator converts a rectangular area measured in feet into square meters. It multiplies square feet by 0.09290304, a factor that comes from squaring the foot's 0.3048 meter definition. A 10 ft by 10 ft space is 100 sq ft, or 9.290 sq m.

How to Calculate Square Meters

Area in square feet (length × width) times 0.09290304 gives the area in square meters. That is the exact, internationally defined conversion factor between square feet and square meters.

Example: 10 ft × 10 ft space

A 10 ft × 10 ft space: 1. Area in square feet: 10 × 10 = 100 sq ft 2. Area in square meters: 100 × 0.09290304 = 9.290 sq m

What Is Square Meters?

A square meters calculator converts a rectangular area measured in feet into square meters, useful when working with metric-specified materials, international product specifications, or comparing a US-measured space against a metric figure.

Square Meters: Pros and Cons

Pros

Uses the exact international conversion factor, not a rounded approximation
Gives both square meters and square feet, useful for comparing figures given in either unit
A straightforward, direct conversion with no hidden assumptions

Cons

Assumes a simple rectangular area. An irregular shape needs its area estimated separately
Doesn't convert linear feet or inches directly to meters or centimeters. This calculator is for area specifically
This site otherwise defaults to US customary units throughout. Use this calculator specifically when you need a metric area figure

Frequently Asked Questions

How do I convert square feet to square meters?

Multiply by 0.09290304, the exact conversion factor. 100 sq ft is 100 × 0.09290304 = 9.29 sq m.

Why is the conversion factor 0.09290304 and not a rounder number?

Because it comes from the exact relationship between a foot (defined as exactly 0.3048 meters) and a square foot. Squaring that gives 0.3048² = 0.09290304 exactly, with no rounding involved.

How many square feet are in a square meter?

About 10.764. It is the reciprocal of the sq ft to sq m factor (1 ÷ 0.09290304 ≈ 10.764).

When would I need to convert to square meters?

Common cases include working with a metric-specified product (tile, flooring, or building material sold by the square meter). They also include comparing a US floor plan against an international one, or following a project specification written in metric units.

Does this site use metric units elsewhere?

No. This site is built around US customary units (feet, inches, gallons, pounds) as its primary system, with this and a small number of other calculators available specifically for metric conversions when needed.
