## Kilometers to decimeters conversion factor and formulas

Formula

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

### Multiplication

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

### Division

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

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

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.

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.
