About These Units

About Inch

The inch is a traditional measurement of distance equal to 1/12 of a foot, or exactly 2.54 centimeters. The Old English word "ynce" is derived from the Latin uncia, meaning a 1/12 part. It follows that "inch" and "ounce" actually have the same origin. The inch was originally defined in England in two ways: as the length of three barleycorns laid end to end, or as the width of a man's thumb at the base of the nail.

About Kilometer
