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 US Survey Chain?
The US survey chain (∼20.1168 m) used the US survey foot. This measurement was key in the rectangular survey system that mapped the American frontier.
