The decimetre (or {{#invoke:Lang|lang}} in American English; symbol: dm), is a unit of length in the International System of Units, equal to one tenth of a metre, ten centimetres, one hundred millimetres, and 3.937 inches.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
The common non-SI metric unit of volume, the litre, is defined as one cubic decimetre, although, from 1901 to 1964, there was a slight difference between the two due to the litre being defined using the kilogram rather than the metre.
Markings of a ship's draft are shown in decimeters in most of the world.
