Inches and centimeters are both commonly used for small measurements — screen sizes, body measurements, paper sizes, and hardware dimensions. Converting between them is one of the most frequent unit conversions.
1 Open the Unit Converter
Navigate to the Unit Converter and select the Length category.
2 Select inches to cm
Choose Inches as the source and Centimeters as the target.
3 Enter the value
Type the inch value. The centimeter result appears instantly.
How It Works
The formula is: cm = inches x 2.54. This is an exact conversion (defined, not approximated). For example, 12 inches = 12 x 2.54 = 30.48 cm. Common reference: 1 foot (12 inches) = 30.48 cm, a standard sheet of paper is 8.5 x 11 inches = 21.59 x 27.94 cm.
