Millimeter to centimeter converter

Remember that one millimeter equals 0.1 centimeterTherefore, we can apply the following formula to calculate the distance in centimeters from a given number of millimeters:

d(cm) = d(mm) / 10

By example,If we are not able to calculate how many centimeters are 30 millimeters, we can calculate how many centimeters are 30 millimeters:

d(cm) = 30 mm / 10 = 3cm

As you can see, the conversion from mm to centimeters is very easy since we only have to divide by 10. This makes things much easier, because as you probably already know, dividing by 10 means that you have to move the decimal point one position to the left.
