- 1 kilometer = 100,000 cm (1 × 100,000)
- 10 kilometers = 1,000,000 cm (10 × 100,000)
Where this conversion comes up
Kilometers are used for road distances and altitude outside the US; centimeters for body height, clothing and furniture sizes. A kilometer is 100,000 cm (1,000 m × 100 cm). Mostly a homework and map-scale conversion: on a 1:50,000 map, 1 km on the ground is 2 cm on paper.
Quick estimate
Multiply by 100,000: add five zeros.
Common mistakes
- Dividing instead of multiplying. A centimeter is smaller than a kilometer, so the number of centimeters must come out larger: 0.5 kilometers = 50,000 cm.
