Millimeters (mm) to Centimeters (cm) Converter

This length unit converter dynamically calculates a value you enter in millimeters (mm) and converts it to its equivalent value in centimeters (cm).

How many millimeters (mm) are in a centimeter (cm)? What is the formula for how to convert millimeters to centimeters (mm to cm)?

1 millimeter (mm) = 0.1 centimeter (cm)
So we can say that there is 0.1 centimeter 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 centimeter unit of measurement is 0.1.

Inversely (or reciprocally),

1 centimeter (cm) = 10 millimeters (mm)
So we can say that there is 10 millimeters in 1 centimeter.
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 centimeter unit of measurement is 10.

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 centimeters (mm to cm). Both formulas will yield the same result. The formulas are:

cm = mm ร— 0.1 ย  ย โ†’ This is the formula based on the multiplication conversion factor.

and

cm = mm รท 10 ย  ย โ†’ This is the formula based on the division conversion factor.

For example, if you have a length of 75 millimeters that you want to convert to centimeters, you would use either of the two formulas as follows:

cm = 75 mm ร— 0.1 = 7.5 cm
cm = 75 mm รท 10 = 7.5 cm

So, the result is the same using either formula, which is 7.5 centimeters.
