**One kilometer is equal to 100,000 centimeters.** One meter equals 100 centimeters. There are 1,000 meters in one kilometer, and 100 centimeters (1 meter) multiplied by 1,000 equals 100,000 centimeters.

This is a whole number conversion, meaning that a whole number kilometer measurement always divides into a whole number centimeter measurement. This is not the case, however, when dividing a kilometer into an imperial measurement. When divided into imperial measurements, a kilometer equals 39,370.1 inches, 3,280.84 feet or 0.62 mile. The United States and United Kingdom are unique in that the two countries do not use the kilometer as an official measurement for distance.
