Square Feet to Square Yards
Convert square feet (ft²) to square yards (yd²). Both measure surface measurement, and the conversion comes up in real estate, farming, construction work.
The Formula
``
square yards = square feet × 0.111111111111
square feet = square yards × 9
`
One square feet is 0.111111 square yards, and one square yard is 9 square feet.

What Each Unit Is
Square Feet (ft²) — the area of a square one foot on each side, or 0.092903 square metres. The imperial unit US and UK property is advertised in.
Square Yards (yd²) — nine square feet, or 0.836127 square metres. The imperial unit for carpet, turf and concrete.
A Sense of Scale
A bedroom is 120–200 ft²- A US home averages 2,300 ft²
- A parking space is 130 ft²
- Carpet is priced per square yard
- A small rug is about 4 yd²
Precision
The factor 0.111111111111 is rounded. For engineering work carry more digits than the table above, and round only at the end — rounding at each step compounds.
In Code

How Many Decimals Do You Need?
Rounding the factor costs accuracy, and how much depends on the factor. Converting 137 ft² with the factor truncated at each decimal place:
| Decimals kept | Factor | 137 ft² becomes | Error |
|---|---|---|---|
| 0 | 0 | 0 | 100.0000% |
| 1 | 0.1 | 13.7 | 10.0000% |
| 2 | 0.11 | 15.07 | 1.0000% |
| 3 | 0.111 | 15.207 | 0.1000% |
| 4 | 0.1111 | 15.2207 | 0.0100% |
The right number of significant figures is set by your input, not by the converter. If you measured square feet to three significant figures, the answer in square yards is only good to three — writing more digits claims precision the measurement never had.
