221 km2 = 221,000,000 m2. To convert square kilometers to square meters, multiply by 1,000,000: 221 × 1,000,000 = 221,000,000.
How to convert square kilometers to square meters
m2 = km2 × 1,000,000
- 1 km2 = 1,000,000 m2 (and 1 m2 = 0.000001 km2).
- Multiply the amount by the factor: 221 × 1,000,000 = 221,000,000.
- Answer: 221 km2 = 221,000,000 m2.
