Dm is the unit of length of decimeter. Decimeter, abbreviated as dm, means decimeter, 1dm( 1 decimeter) =10cm (10cm); 1m (1m) =10dm (10 decimeter) = 100cm( 100 cm).

Mathematical length units Mathematical length units are kilometers, decimeters, centimeters, millimeters, microns and so on. These units of length are often used in mathematics and physics. The unit of length is a commonly used basic unit, which is mainly used to measure spatial distance. In practical application, if the length units are different, it is necessary to convert the length units. The commonly used kilometer is equal to 1000 meter, one meter is equal to ten meters, one minute is equal to ten centimeters, and one centimeter is equal to ten millimeters.

Mathematical length unit conversion 1 m = 10 decimeter.

1 decimeter = 10/0cm

1 cm = 10/0mm

1 km =1000m

1 m = 100 cm

1m = 1000mm

1 mm = 1000 micron

1 m = 10 decimeter = 100 cm

1cm = 1cm = 0.0 1m
