How to convert Decimetre to Kilometre
To convert Decimetres to Kilometres, multiply the value by 0.0001.
- Take your measurement in Decimetres.
- Multiply it by 0.0001 — the number of Kilometres in one Decimetre.
- The result is the same amount, expressed in Kilometres.
To go the other way, multiply Kilometres by 10,000 — or simply divide by 0.0001.
For example, a full metre (ten decimetres) is about 10 dm, which is 0.001 km.
About Decimetre and Kilometre
A decimetre is one-tenth of a metre, or 10 centimetres. It is rarely used in daily life but appears in science — a cubic decimetre is exactly one litre.
A kilometre is 1,000 metres, the standard metric unit for longer distances. It is used for road distances, running races and geography almost everywhere outside the United States and the United Kingdom.
Both the Decimetre and the Kilometre are metric units, so converting between them is just a change of scale: one Decimetre equals 0.0001 Kilometres, and the Kilometre is the larger unit.
