Converting centimeters to inches comes up constantly — screen sizes, paper dimensions, clothing measurements and international shipping labels all mix the two systems. The exact relationship is that one inch equals 2.54 centimeters, so to go from centimeters to inches you divide by 2.54. A 30 cm ruler, for example, is very close to 11.8 inches.

Because the factor is fixed by definition rather than measured, centimeter-to-inch conversions are exact and never drift. That is unlike, say, currency rates. If you only need a quick estimate, dividing by 2.5 gets you within about 2% — good enough for guessing a TV size but not for a machine part.

A frequent source of error is confusing height notation. A person listed as 170 cm is about 5 feet 7 inches, not 5.7 feet — remember that after converting to inches you still have to split the result into feet and inches, with 12 inches to a foot.
