How many decimeters are there in a millimeter? Use this online tool to quickly convert from millimeters to decimeters (mm to dm) and vice versa.
How Many Decimeters in a Millimeter?
Since one millimeter equals precisely 0.01 decimeters, the conversion factor is 1 millimeter = 0.01 decimeters.
To find the comparable length or distance in decimeters, multiply the provided number of millimeters by the conversion factor. This will convert millimeters to decimeters.
Decimeters to millimeters can be converted using the opposite procedure. To obtain the equivalent length or distance in millimeters, divide the specified number of decimeters by the conversion factor.
Difference Between Millimeters and Decimeters
The main distinctions between millimeters and decimeters are the units of length they represent, their respective conversion factors, and their uses and applications.
| Characteristics | Millimeters (mm) | Decimeters (dm) |
|---|---|---|
| Unit of Length | A millimeter is used as a unit of length. It is the smallest measurement found on a metric ruler, approximately the size of the wire on a standard paper clip. Its Latin prefix, mille, means one thousand. So, millimeter translates to one-thousandth of a meter. | The decimeter is one of the lesser-known units of length or distance. Its Latin prefix, deci, which is short for decimus, means one-tenth. As such, a decimeter means one-tenth of a meter. It is ten times larger than a centimeter and is not found on a standard metric ruler. |
| Uses and Applications | Used to measure small but visible objects and narrow distances | Used commonly to measure a ship’s draft markings in most parts of the world |
| Conversion Factor | 1 millimeter is exactly equal to 0.01 decimeters | 1 decimeter is exactly equal to 100 millimeters |
Similarity Between Millimeters and Decimeters
Both units of measurement are part of the International System of Units (SI) which was developed in France. This system of measurement is widely used in technology, science, commerce, and industry, and has largely replaced the old-fashioned Imperial system, which includes the miles, yards, etc.
How to Convert Millimeters to Decimeters?
These units of measurement can be mathematically equated to each other using the conversion factor 1 millimeter = 0.01 decimeters. Here is the mathematical operation in detail:
Formula:
Decimeters = Millimeters x 0.01
Task:
Convert 25,397 millimeters to decimeters
Calculation:
Number of Decimeters = 25397 x 0.01 = 253.97 decimeters
Therefore, 1,935 millimeters is equivalent to 253.97 decimeters.
Millimeters to Decimeters (mm to dm) Conversion Table
For the ranges of 1 to 10, 10 to 100 for every multiple of 10, and 100 to 1,000 for every multiple of 100, simply convert millimeters to decimeters using the table below:
