About Centimeter and Inch

The centimeter is one hundredth of a meter (10 millimeters). It is the everyday small-length unit in metric countries, used where inches would be used in the US. The inch is defined as exactly 25.4 millimeters, one twelfth of a foot. Screen sizes, pipe diameters, and US manufacturing drawings are specified in inches. One Centimeter equals 0.3937007874 Inches (1 cm = 0.3937007874 in). Centimeter is used in body height and clothing measurements and in furniture and interior dimensions. Inch is used in screen and display sizes.

Precision and Rounding:Length factors between metric and imperial units are exact by definition (1 ft = 0.3048 m since 1959), so any rounding error comes from display precision, not the factor. Two or three decimal places suit carpentry and DIY work; machining and surveying often require four or more.

Conversion factors per NIST Special Publication 811 and the BIPM SI Brochure (9th edition) (reference).
