What is a Fermi?
A fermi equals 1 femtometer (10⁻¹⁵ m), honoring physicist Enrico Fermi. This unit describes nuclear dimensions - a proton is about 1.68 fermis across. Particle physicists prefer 'femtometer' but retain 'fermi' in colloquial usage.
What is a Cloth Span?
A span represented 9 inches (22.86 cm), the distance between thumb and little finger when spread. Medieval cloth merchants used this measurement, with 2 spans making 1 cubit. The term survives in 'spanner' tools adjusting span-width nuts.
