Convert Millimeters to Centimeters
This conversion helps when you measure small objects and need the result in centimeters.
It is common in school work, craft projects, and quick size checks.
Quick Answer
1 Millimeter = 0.1 Centimeters
Example 1: 25 mm = 2.5 cm
Example 2: 80 mm = 8 cm
Conversion Formula
Formula: centimeters = millimeters ÷ 10
This means you divide the millimeter value by 10 to get centimeters, because 10 millimeters make 1 centimeter.
- Write the number in millimeters.
- Divide it by 10.
- The result is the value in centimeters.
What Is Millimeter
A millimeter is a metric unit of length, equal to one thousandth of a meter. It is very small and used for precise measurements.
- Thickness of paper, cards, and plastic sheets
- Small parts like screws, bolts, and washers
- Engineering and 3D printing measurements
- Ruler markings for fine detail
- Medical and lab measurements where precision matters
What Is Centimeter?
A centimeter is a metric unit of length, equal to one hundredth of a meter. It is larger than a millimeter and used for everyday measuring.
- Measuring height and body sizes
- School projects and geometry drawings
- Clothing and fabric measurements
- Packaging sizes and product dimensions
- Household measuring with a tape measure
Real Life Examples
Here are common situations where you might switch from millimeters to centimeters.
- A phone case thickness is 12 mm, that is 1.2 cm.
- A pencil is 7 mm wide, that is 0.7 cm.
- A small bolt length is 35 mm, that is 3.5 cm.
- A notebook cover is 210 mm tall, that is 21 cm.
- A tile spacer is 3 mm, that is 0.3 cm.
- A bracelet bead is 8 mm, that is 0.8 cm.
- A drawer handle screw is 45 mm, that is 4.5 cm.
- A cut line on a craft sheet is 150 mm, that is 15 cm.
Quick Tips
- To convert mm to cm, move the decimal one place left.
- Divide by 10 is the same as shifting one digit left.
- 10 mm = 1 cm, use this as a quick checkpoint.
- For whole centimeters, look for multiples of 10 mm like 20, 30, 40.
- If the mm number ends in 5, the cm result ends in .5 after dividing by 10 (example 25 mm = 2.5 cm).
- When precision matters, keep one decimal place in centimeters.
