How to convert centimeters to kilometers
1 centimeter = 0.00001 kilometers. To convert centimeters to kilometers, divide by 100,000 (or multiply by 0.00001). A centimeter is one hundredth of a meter. A kilometer is 1,000 meters.
Worked examples
- 500 centimeters = 0.005 km (500 ÷ 100,000)
- 25,000 centimeters = 0.25 km (25,000 ÷ 100,000)
- 100,000 centimeters = 1 km (100,000 ÷ 100,000)
Where this conversion comes up
Centimeters are used for body height, clothing and furniture sizes; kilometers for road distances and altitude outside the US. Divide by 100,000: 25,000 cm is 0.25 km and 100,000 cm is 1 km. Comes up with map scales, where 1 cm on a 1:25,000 map is 0.25 km on the ground.
Quick estimate
Move the decimal point five places left.
Common mistakes
- Multiplying instead of dividing. A kilometer is larger than a centimeter, so the number of kilometers must come out smaller: 500 centimeters = 0.005 km.
