Square Kilometers to Square Yards
Convert square kilometers (km²) to square yards (yd²). Both measure surface measurement, and the conversion comes up in real estate, farming, construction work.
The Formula
``
square yards = square kilometers × 1195990.0463
square kilometers = square yards × 8.3612736e-7
`
One square kilometer is 1,195,990.05 square yards, and one square yard is 8.3613e-7 square kilometers.

What Each Unit Is
Square Kilometers (km²) — one million square metres. The metric unit for regions, cities and land cover.
Square Yards (yd²) — nine square feet, or 0.836127 square metres. The imperial unit for carpet, turf and concrete.
A Sense of Scale
Central Park is 3.4 km²- Manhattan is 59 km²
- Greater London is 1,572 km²
- Carpet is priced per square yard
- A small rug is about 4 yd²
Precision
The factor 1195990.0463 is rounded. For engineering work carry more digits than the table above, and round only at the end — rounding at each step compounds.

How Many Decimals Do You Need?
Rounding the factor costs accuracy, and how much depends on the factor. Converting 137 km² with the factor truncated at each decimal place:
| Decimals kept | Factor | 137 km² becomes | Error |
|---|---|---|---|
| 0 | 1195990 | 163,850,630 | — |
| 1 | 1195990 | 163,850,630 | — |
| 2 | 1195990.05 | 163,850,636.85 | — |
| 3 | 1195990.046 | 163,850,636.3 | — |
| 4 | 1195990.0463 | 163,850,636.34 | — |
The right number of significant figures is set by your input, not by the converter. If you measured square kilometers to three significant figures, the answer in square yards is only good to three — writing more digits claims precision the measurement never had.
