Micrometer
From Wikinfo
A micrometer is a device for precisely measuring small distances or thicknesses. The precision is often achieved by a screw mechanism.
Micrometer is also the U.S. spelling of micrometre, a millionth of a metre or meter. This word is pronounced with stress on the first syllable; the name of the measuring device is stressed on the second.
