Use this calculator to convert millimeters to centimeters. Enter a length in millimeters, with decimals if you need them, and you get the same length in centimeters, in meters, and broken down into meters, centimeters and millimeters.
Below you will find the formula, worked examples and a table of the most common conversions.
How to use the millimeters to centimeters calculator
Step 1: Type the length in millimeters in the box. You can use a decimal point or a comma, for example 12.5 or 12,5.
Step 2: Click Calculate or press the Enter key.
Step 3: The result in centimeters appears in the panel on the right. Below it you will see the same length in meters and in meters, centimeters and millimeters.
Step 4: The Calculation box shows the operations with your numbers.
Formula to convert millimeters to centimeters
One centimeter is exactly 10 millimeters. So to go from millimeters to centimeters, divide by 10:
| d(cm) = d(mm) ÷ 10 |
Dividing by 10 is the same as moving the decimal point one place to the left: 25 mm becomes 2.5 cm. To convert millimeters to meters, divide by 1000.
Millimeters to centimeters examples
Example 1: How many centimeters is 25 mm?
d(cm) = 25 ÷ 10 = 2.5 cm
A screw that is 25 mm long is 2.5 cm long.
Example 2: Convert 7 mm to centimeters
d(cm) = 7 ÷ 10 = 0.7 cm
That is less than one centimeter: seven tenths of one.
Example 3: Convert 1725 mm to centimeters and meters
d(cm) = 1725 ÷ 10 = 172.5 cm
d(m) = 1725 ÷ 1000 = 1.725 m
In meters, centimeters and millimeters that is 1 m 72 cm 5 mm.
Example 4: Convert 0.8 mm to centimeters
d(cm) = 0.8 ÷ 10 = 0.08 cm
This is the kind of value you meet with thin sheets or fine wire.
