To convert decimeters to millimeters (dm to mm) or to convert millimeters to decimeters (mm to dm), you may use the converter above. Alternatively, to find out how many millimeters there are in "x" decimeters, you may use the decimeters to millimeters table.
Below, you will find information of how to convert dm to mm and how to convert mm to dm, including the formulas and example conversions.
How many millimeters in a decimeter?
1 Decimeter (dm) is equal to 100 millimeters (mm). To convert decimeters to millimeters, multiply the decimeter value by 100.
For example, to find out how many millimeters there are in 2 decimeters, multiply 2 by 100, that makes 200 mm in 2 dm.
dm to mm formula
mm = dm * 100
How to convert millimeters to decimeters?
1 Millimeter (mm) is equal to 0.01 decimeter (dm). To convert millimeters to decimeters, multiply the millimeter value by 0.01 or divide by 100.
mm to dm formula
dm = mm * 0.01
dm = mm / 100
