CM to MM

Convert centimeters (cm) to millimeters (mm) with formulas, examples, and conversion tables.

Centimeters (cm)

Millimeters (mm)

1 cm = 10 mm

Full precision:10 mm

Feet + Inches:1' 3.5"

Step-by-Step Solution

To convert 1 centimeters to millimeters, we multiply by 10 because one centimeter equals exactly 10 millimeters.

1 centimeter = 10 millimeters

Since each centimeter contains 10 millimeters, we multiply our value by this factor:

1 × 10 = 10 millimeters

So 1 centimeters = 10 millimeters.

✓Quick check: 10 ÷ 10 = 1 centimeters

How to Convert Centimeters to Millimeters

To convert centimeters to millimeters, multiply the value by 10.

Millimeters = Centimeters × 10

1 centimeter = 10 millimeters

Tip: To convert millimeters back to centimeters, divide by 10.

Example 1: 1 cm = 10 mm
1 × 10 = 10

Example 2: 5 cm = 50 mm
5 × 10 = 50

Example 3: 10 cm = 100 mm
10 × 10 = 100
