Why is 'lb' the abbreviation of the measurement of a pound?

Question

There is no "L" or "B" in the spelling of the word 'pound', so why is it abreviated as such?

Answer 1

"Lb." stands for libra, the basic unit of Roman weight, from which our present-day pound derives.

Answer 2

The abbreviation comes from "libras" which was the unit of measurement in Roman times. As a sidenote, the word "libra" is the translation for both the unit of weight and the British unit of currency, the Pound, in more than one Latin-derived language.

Answer 3

[Q] From Andrea: “Why are pounds, when used as a weight, abbreviated lbs?”

[A] The origin is in the Latin word libra, which could mean both balance scales (hence the symbol for the astrological sign Libra, which was named after a constellation that was thought to resemble scales) and also a pound weight, for which the full expression was libra pondo, the second word being the origin of our pound.

Answer 4

lb comes from the Latin libra which is a unit similar to a pound. The word pound comes from the Latin pendere meaning to weigh.
