Millimeters (mm) to Decimeters (dm) Converter

This length unit converter dynamically calculates the value you enter in millimeters (mm) and converts it to its equivalent value in decimeters (dm).

How many millimeters (mm) are in 1 decimeter (dm)? What is the formula for how to convert millimeters to decimeters (mm to dm)?

1 millimeter (mm) = 0.01 decimeter (dm)
So we can say that there is 0.01 decimeter in 1 millimeter.
This means that the multiplication conversion factor to convert a quantity expressed in a millimeter unit of measurement to an equivalent quantity expressed in a decimeter unit of measurement is 0.01.

Inversely (or reciprocally),

1 decimeter (dm) = 100 millimeters (mm)
So we can say that there are 100 millimeters in 1 decimeter.
This means that the division conversion factor to convert a quantity expressed in a millimeter unit of measurement to an equivalent quantity expressed in a decimeter unit of measurement is 100.

Knowing this inverse mathematical relationship between the two conversion factors and their reciprocal operations, we can derive two formulas to calculate and convert a quantity of length expressed in millimeters to an equivalent quantity of length expressed in decimeters (mm to dm). Both formulas will yield the same result. The formulas are:

dm = mm ร— 0.01 ย  ย โ†’ This is the formula based on the multiplication conversion factor.

and

dm = mm รท 100 ย  ย โ†’ This is the formula based on the division conversion factor.

For example, if you have a length of 37.5 millimeters that you want to convert to decimeters, you would use either of the two formulas as follows:

dm = 37.5 mm ร— 0.01 = 0.375 dm
dm = 37.5 mm รท 100 = 0.375 dm

So, the result is the same using either formula, which is 0.375 decimeter.

The abbreviation for millimeter is mm. The single Unicode character ใŽœ (U+339C) represents the 2-character Latin abbreviation for millimeter. The Windows Alt code for this character ใŽœ is Alt + 13212.

What is a decimeter (dm)?

Definition of decimeter: A decimeter is a unit of length in the International System of Units (SI), commonly known as the metric system. It is equivalent to one tenth of a meter (0.1 m). It is less commonly used than centimeters or meters but can be useful for intermediate measurements.

The abbreviation for decimeter is dm. The single Unicode character ใท (U+3377) represents the 2-character Latin abbreviation for decimeter. The Windows Alt code for this character ใท is Alt + 13175.
