Answer 2

The word “pound” comes from the Latin word pendere, meaning “to weigh”. The Latin word libra means “scales, balances" and it also describes a Roman unit of mass similar to a pound. This is the origin of the abbreviation “lb” or “℔” for the pound. The “s” at the end of “lbs” simply denotes the plural form.

Answer 4

you mean lb, right? The word “pound” comes from the Latin word pendere, meaning “to weigh”. The Latin word libra means “scales, balances" (so in the zodiac, libra is represented by a pair of scales) and it also describes a Roman unit of mass similar to a pound. This is the origin of the abbreviation “lb” or “℔” for the pound.
