## Decimeters to kilometers conversion factor and formulas

Formula

The conversion factor between decimeters and kilometers is 10,000. This represents the ratio of decimeters per one kilometer. To calculate the value in kilometers, we can either divide by the conversion factor or multiply by its inverse.

### Division

To convert from decimeters to kilometers, divide decimeters by 10,000.
The formula is expressed as:
dm ÷ 10,000 = km

### Multiplication

Alternatively we can multiply by the inverse conversion factor to get the same result.
The inverse of 10,000 is 1/10,000 or 0. To convert from decimeters to kilometers, multiply decimeters by 0.
The formula is expressed as:
dm × 0 = km

A conversion from decimeters to kilometers are units within in the metric (SI) or SI compatible systems.

SI Unit

Within the SI (metric) system of measurement, the decimeter is officially defined as one tenth (1/10) of a meter. The decimeter is not widely used in everyday situations. Internationally it is spelled 'decimetre' whereas the U.S. spells it 'decimeter'. The symbol for decimeters is dm.

SI Unit

Within 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.
