How to Convert Square Yard to Square Kilometre
- 1 yd² = 8.3612736 × 10⁻⁷ km²
- 1 km² = 1195990.046 yd²
- Example: convert 15 yd² to km²: 15 yd² = 15 × 8.3612736 × 10⁻⁷ km² = 0.0000125419104 km²
Formula
km² = yd² × 8.3612736 × 10⁻⁷
or km² = yd² ÷ 1195990.046301
Derivation from SI units:
- 1 yd² = (0.9144 m)² = 0.83612736 m² = 9 ft²
- 1 km² = (1000 m)² = 10⁶ m² = 100 ha
- 1 yd² = 0.83612736 m² ÷ 1000000 m² per km² = 8.3612736 × 10⁻⁷ km²
Both units are defined exactly, so the factor is exact. Square Yard definition: square yard; Square Kilometre definition: square kilometre.
Worked examples
- A reading of 20 yd² converts to 0.0000167225472 km².
20 yd² × 8.3612736 × 10⁻⁷ = 0.0000167225472 km² - A value of 200 yd² is 0.000167225472 km².
200 yd² × 8.3612736 × 10⁻⁷ = 0.000167225472 km²
