The units list is hilarious and amazingly detailed, a sample:
crocodile := megavolt // used informally in UK physics labs
...
footcandle := lumen/ft^2 // Illuminance from a 1 candela source
// at a distance of one foot
...
// In Britain, the deal is apparently any piece of wood over 6 feet long, over
// 7 wide and 2.5 inches thick. The OED doesn't give a standard size. A piece
// of wood less than 7 inches wide is called a "batten". This unit is now used
// exclusively for fir and pine.
deal := 12 ft 11 in 2.5 in // The standard North American deal [OED]
wholedeal := 1/2 deal // If it's half as thick as the standard
// deal it's called a "whole deal"!
splitdeal := 1/2 wholedeal // And half again as thick is a split deal.
...
parasang := 3.5 mile // Persian unit of length usually thought
// to be between 3 and 3.5 miles
