From centimeters to millimeters easily with our online converter. Its operation is very simple since you only have to enter the length in centimeters that you want to convert to millimeters and press the calculate button.
If you wish, we also have at your disposal the mm to cm converter which performs the opposite operation.
How to convert from cm to mm
One centimeter equals 10 millimeters. so from this data, we can apply the following formula to make the conversion from cm to mm:
d(mm) = d(cm) × 10
For example, if we want to pass 20 centimeters to millimeters:
d(mm) = 20 cm × 10 = 200 millimeters
How much is 1 cm equivalent to mm?
When we forget the equivalence between these two units of length, we tend to hesitate in a conversion as obvious as the one in this section. How many millimeters does a centimeter equal?
As we have said before, one centimeter is 10 millimeters. Remember that the scale of units of the international system follows this order:
When we move from one unit to a lower level unit, we have to multiply by 10 each time we make a jump. In this case, since centimeters and millimeters are together, we only make one jump and therefore, a multiplication by ten.
Remember: 1 cm = 10 mm
If we change the units the other way around, that is, we start from one unit and we want to convert it to a higher level, then we must divide by 10. In our case, if we want to change from 1 millimeter to centimeters, it would look like this:
1 mm = 0.1 cm
Convert cm to mm in Excel
If you want to convert centimeters to millimeters using ExcelThere is a specific function in the Microsoft program that will allow you to calculate the equivalence between these two units of length.
To do this, open a new spreadsheet and in an empty cell type the following formula:
=CONVERT(length; "cm"; "mm")
Just replace the word length with the number of centimeters you want to convert to millimeters. For example, if you want to know how many is 50 cm to mmthe function will look like this:
=CONVERT(50; "cm"; "mm")
You also have the option of typing in the coordinates of a cell to create your own cm to mm converter. In the photo above these lines we have used cell "C2", so that every time we change its value, the equivalence in millimeters will automatically appear in the cell below.

How is it measured in mm?
If you have a ruler or tape measure handy, you will be able to see that has a series of lines marked along its entire length.
The numbers indicate the number of centimeters while all the numbers indicate the number of centimeters. the smallest lines between each cm are millimeters..
If you count them all, you will see that 10 lines make 1 centimeter and as we saw at the beginning, we need 10 millimeters to make one centimeter.
