Millimeters to Decimeters: the quick answer
1 mm = 0.01 dm
1 millimeter equals 0.01 decimeters
To convert millimeters to decimeters, multiply the value by 0.01. To go the other way, multiply decimeters by 100 to get millimeters.
To convert millimeters to decimeters, multiply the value by 0.01. To go the other way, multiply decimeters by 100 to get millimeters.

Millimeter (mm). A millimeter is one thousandth of a meter, used for small measurements such as thickness and rainfall.
Decimeter (dm). A decimeter is one tenth of a meter (10 centimeters), used mostly in schools and some sciences.
There are 0.01 decimeters in one millimeter.
Multiply the number of millimeters by 0.01. For example, 10 millimeters equal 0.1 decimeters.
One decimeter equals 100 millimeters.
0.12 decimeters. Other common values: 5 millimeters = 0.05 decimeters and 100 millimeters = 1 decimeter.
