Current Use
The micrometer is a common unit for measuring the wavelength of infrared radiation, as well as the size of biological cells and bacteria. It is also widely used in technology and engineering.
Millimeter
A millimeter is a unit of length in the metric system, equal to one-thousandth of a meter.
History/Origin
The prefix "milli-" comes from the Latin word "mille," meaning thousand. The millimeter was part of the original metric system adopted in France in 1795.
