What is a US Survey Inch?
The US survey inch (1/39.37 meter ≈ 2.540005 cm) was slightly longer than the international inch (2.54 cm). Used in all American engineering drawings until 2023, its difference caused measurable discrepancies in large-scale projects.
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.
