Worked example
How large is a 20 m² room in square feet?
Problem
A room has a floor area of 20 m². You need the same area in square feet for a US-style floor plan.
Solution
20 m² is approximately 215.278 ft².

How the conversion works
Every area factor is the square of the matching length factor, which is why these numbers look unfamiliar next to the ones you already know. A foot is exactly 0.3048 m, so a square foot is 0.3048 squared: exactly 0.09290304 m². Your value is converted to square metres on that basis and then to the unit you asked for. Squared factors rarely divide evenly — one square metre is 10.76391 square feet and the decimals continue — so a result that does not terminate is rounded for display and marked as approximate.
Supported units
Hectares and acres are land measures rather than SI units, so they carry defined equivalents instead of being derived from a base unit: a hectare is exactly 10,000 m², and an international acre is exactly 4,046.8564224 m², which is 43,560 square feet. Area never converts into length or volume. Those are different dimensions and each has its own converter.
