ABBREVIATION LB FOR POUND

[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.
