What is an Ell?
The ell was a medieval cloth measurement ranging from 27-45 inches (69-114 cm) across Europe. The English ell measured 45 inches (1.143 m), while the Scottish ell was longer at 37 inches (94 cm). Derived from the Latin 'ulna' (arm), it represented the length from elbow to fingertip plus an extra hand span for cloth merchants.
What is a Fermi?
