Span (Cloth)
A span is an obsolete unit of length, typically about 9 inches, based on the distance between the tip of the thumb and the tip of the little finger when the hand is fully extended.
History/Origin
The span has been used as a unit of measurement for thousands of years in many different cultures.
Current Use
The span is no longer a standard unit of measurement.
Fermi
A fermi is a unit of length equal to a femtometer, which is 10⁻¹⁵ meters.
History/Origin
The fermi is named after the Italian-American physicist Enrico Fermi. It was a popular unit in nuclear physics.
Current Use
The femtometer is the officially recognized SI unit, but the fermi is still used informally in nuclear and particle physics.
