Square kilometers to square centimeters

1 square kilometer in square centimeters
1 km² = 10,000,000,000 cm²
cm² = km² × 10,000,000,000

To convert square kilometers to square centimeters, multiply by 10,000,000,000. The table below gives the values people look up most often, and the converter works for any number.

How the conversion works

The relationship is cm² = km² × 10,000,000,000. Both units measure area, so the conversion is a fixed factor that never changes.

Common questions

How many square centimeters are in one square kilometer?
One square kilometer equals 10,000,000,000 square centimeters. cm² = km² × 10,000,000,000.
How do you convert square kilometers to square centimeters?
Use cm² = km² × 10,000,000,000. So 10 km² is 100,000,000,000 cm².
How many square kilometers are in one square centimeter?
One square centimeter equals 1 × 10^-10 square kilometers, which is the reverse of the conversion above.
