The converter above starts at 15 cm and also shows the length to the nearest sixteenth of an inch, the way a U.S. tape measure is marked: 5 7/8 in. For other lengths, use the full cm to inches converter; to go the other way, inches to cm.

15 cm and 6 inches are often treated as the same size, and for most purposes they are: a 6-inch ruler is 15.24 cm long, so 15 cm falls 2.4 mm short.
