Femtometer
A femtometer is a unit of length in the metric system equal to 10^-15 meters. It is also known as a fermi.
History/Origin
The prefix "femto-" for 10^-15 was adopted by the CGPM (General Conference on Weights and Measures) in 1964. The unit is also named after the physicist Enrico Fermi.
Current Use
The femtometer is primarily used in nuclear physics to measure the size of atomic nuclei.
Meter
The meter is the base unit of length in the International System of Units (SI). It is the length of the path travelled by light in a vacuum in 1/299,792,458 of a second.
History/Origin
The meter was originally defined in 1793 as one ten-millionth of the distance from the equator to the North Pole. This changed in 1889, when the international prototype meter was established as the length of a prototype meter bar, made of an alloy of platinum and iridium. In 1960, the meter was redefined in terms of a certain number of wavelengths of a certain emission line of krypton-86.
Current Use
The meter is used worldwide in many applications such as science, engineering, and trade. The United States is one of the few countries in which the meter is not widely used in everyday life and trade.
