231 m2 = 0.000231 km2. To convert square meters to square kilometers, divide by 1,000,000: 231 ÷ 1,000,000 = 0.000231.
How to convert square meters to square kilometers
km2 = m2 × 0.000001
- 1 m2 = 0.000001 km2 (and 1 km2 = 1,000,000 m2).
- Multiply the amount by the factor: 231 × 0.000001 = 0.000231.
- Answer: 231 m2 = 0.000231 km2.
Shortcut: dividing by 1,000,000 gives the same result as multiplying by 0.000001.
