The precise fraction answer is **100,000 ^{0}/_{1} cm**.

### Decimal Precision

Conversion from one to ten decimal places

- 1 km =
**100,000.0 cm** - 1 km =
**100,000.00 cm** - 1 km =
**100,000.000 cm** - 1 km =
**100,000.0000 cm** - 1 km =
**100,000.00000 cm** - 1 km =
**100,000.000000 cm** - 1 km =
**100,000.0000000 cm** - 1 km =
**100,000.00000000 cm** - 1 km =
**100,000.000000000 cm** - 1 km =
**100,000.0000000000 cm**

## About Kilometers

SI UnitWithin the SI (metric) system of measurement, the kilometer is officially defined as being equal to 1,000 meters. It is commonly used as measurement for geographic distances in similar circumstances where a mile would be used in the U.S. Internationally it is spelled 'kilometre' whereas the U.S. spells it 'kilometer'. The symbol for a kilometer is km however k is sometimes used.

## About Centimeters

SI UnitWithin the SI (metric) system of measurement, the centimeter is officially defined as one hundredth (1/100) of a meter. It is commonly used as measurement from shorter lengths. Internationally it is spelled 'centimetre' whereas the U.S. spells it 'centimeter'. The symbol for centimeters is cm.

## Reverse this conversion

## 1 kilometers to other length units

### Metric

- 1 km =
**1 km** - 1 km =
**1,000 m** - 1 km =
**10,000 dm** - 1 km =
**100,000 cm** - 1 km =
**1,000,000 mm** - 1 km =
**1×10**^{9}µ - 1 km =
**1×10**^{12}nm

### Imperial/U.S.

- 1 km =
**0.621 mi** - 1 km =
**1,093.613 yd** - 1 km =
**3,280.84 ft** - 1 km =
