# Centimeters to Kilometers (cm to km)

Source: https://www.unitconvertercalculator.com/length/centimeters-to-kilometers/

**1 cm = 1.0E-5 km**

One centimeter equals exactly 0.00001 kilometers (10-5 km). This conversion moves five steps up the metric prefix ladder. One hundred thousand centimeters make one kilometer. The metric system makes this trivially simple: just move the decimal point five places.

## Formula

Convert Centimeters to Kilometers

## Conversion Table

| Centimeters (cm) | Kilometers (km) |
|---|---|
| 1 cm | 1.0E-5 km |
| 10 cm | 0.0001 km |
| 100 cm | 0.001 km |

## Units

### Centimeter (cm)

A metric unit of length equal to one hundredth of a meter. Commonly used for body height, clothing sizes, and everyday measurements.

### Kilometer (km)

A metric unit of length equal to 1000 meters. The standard unit for measuring road distances and geographic distances in most countries.

## Background

A kilometer is 100,000 cm. A 5K race is 500,000 cm. A person 175 cm tall is 0.00175 km. While nobody expresses height in kilometers, the conversion demonstrates the metric system's scalability: every step is a factor of 10, all the way from centimeters to kilometers.

## Good to Know

The metric system was designed so that cm-to-km is exactly 105. No memorizing 5,280 or 1,760 or 63,360. Just move the decimal point. This simplicity is why 95% of the world uses metric for distance.

## FAQ

### How many kilometers is 1 centimeter?

One centimeter equals exactly 0.00001 km (10-5 km). Move the decimal point 5 places left.

### How many centimeters are in 1 kilometer?

One kilometer contains exactly 100,000 centimeters (105 cm).

### When would I use this conversion?

Rarely directly. The metric system's strength is that you can scale between any prefix pair by moving the decimal point. Cm to km is 5 places left.

## Non-Frequently Asked Questions

### How many centimeters do I walk in a lifetime?

The average person walks about 150,000 km in a lifetime. That is 15 billion centimeters, or 15,000,000,000 cm. If you counted one centimeter per second, it would take you 475 years to count them all. Walking is faster than counting.
