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

1 centimeter (cm) = 10 millimeters (mm)
So we can say that there are 10 millimeters in 1 centimeter.
This means that the multiplication conversion factor to convert a quantity expressed in a centimeter unit of measurement to an equivalent quantity expressed in a millimeter unit of measurement is 10.

Inversely (or reciprocally),

1 millimeter (mm) = 0.1 centimeter (cm)
So we can say that there is 0.1 centimeter in 1 millimeter.
This means that the division conversion factor to convert a quantity expressed in a centimeter unit of measurement to an equivalent quantity expressed in a millimeter unit of measurement is 0.1.

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 centimeters to an equivalent quantity of length expressed in millimeters (cm to mm). Both formulas will yield the same result. The formulas are:

mm = cm × 10    → This is the formula based on the multiplication conversion factor.

and

mm = cm ÷ 0.1    → This is the formula based on the division conversion factor.

For example, if you have a length of 8 centimeters that you want to convert to millimeters, you would use either of the two formulas as follows:

mm = 8 cm × 10 = 80 mm
mm = 8 cm ÷ 0.1 = 80 mm

So, the result is the same using either formula, which is 80 millimeters.
