About Kilometers

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.

About Decimeters

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.
