How to convert kilometers to centimeters

One kilometer is 100,000 centimeters, so multiply the number of kilometers by 100,000. For example, 20 kilometers is 20 × 100,000 = 2,000,000 centimeters. To go back, divide by the same number, or multiply by 0.00001.

Quick estimate

Multiplying by about 100000 gets within 0.0% of the exact answer, which is enough to check that a result makes sense.
