Kilometers to Centimeters (km to cm) Converter
1 kilometer (km) = 100,000 centimeters (cm). To convert kilometers to centimeters, multiply by 100,000: 5 km × 100,000 = 500,000 cm. Also searched as kms to centimeter, kilometre to centimeter, kilometres to centimetres.
Quick facts
- 1 km = 100,000 cm
- 1 cm = 0.00001 km
- Formula: cm = km × 100,000
- Quick estimate: multiply by about 100000
How to convert kilometers to centimeters
- Take the value in kilometers.
- Multiply it by 100,000 (the number of centimeters in one kilometer).
- Round the result to the precision you need.
Worked example (a 5K run): 5 km × 100,000 = 500000 cm.
To convert centimeters back to kilometers, multiply by 0.00001, or divide by 100,000.
