Decimeter (dm). A decimeter is one tenth of a meter (10 centimeters), used mostly in schools and some sciences.
Millimeter (mm). A millimeter is one thousandth of a meter, used for small measurements such as thickness and rainfall.
There are 100 millimeters in one decimeter.
Multiply the number of decimeters by 100. For example, 10 decimeters equal 1,000 millimeters.
One millimeter equals 0.01 decimeters.
1,200 millimeters. Other common values: 5 decimeters = 500 millimeters and 100 decimeters = 10,000 millimeters.
