As the title states. Most other English abbreviations are exactly that, "ft" for foot, "in" for inch, and at least "oz" for ounce has one of the letters. But then you have pound and the abbreviation has no relationship whatsoever to the word...

The word 'pound' is abbreviated 'lb.' after the constellation 'libra' because it means 'pound' in Latin, and also 'scales'. The abbreviation for the British Pound Sterling comes from the same source: it is an 'L' for Libra/Lb. with a stroke through it to indicate abbreviation. Sames goes for the Italian lira which uses the same abbreviation ('lira' coming from 'libra'). So British currency (before it went metric) was always quoted as "pounds/shillings/pence", abbreviated "L/s/d" (libra/solidus/denarius).
