    lb is short for libra, which is the latin word for the Roman version of the pound.

    The symbol pd is used for per diem, a unit of frequency meaning once per day.

      Thanks for the definition. Although, I think my co-worker is reluctant to tell his daughter that. He is afraid that there will be a lot more questions! LOL
      Thanks again!

        By international convention, lb is a unit of measure and thus does not have a plural. So stricly speaking it is incorrect to write 10 lbs; it should be 10 lb without the 's'. This rule applies to all units of measure as, for example, gram whose symbol is 'g'; you wouldn't write 'gs' for grams.

              i know why: the greek word limbs was used for pounds a long time ago. they kept the abbriveation, but changed limbs to pounds. i don't know why!

                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” for the pound. The “s” at the end of “lbs” simply denotes the plural form.

                  Oy. Thanks to those whose answers seem to have fallen on deaf ears...
                  (PS As already stated, lbs. is incorrect, although it has been gaining acceptance in the world of sloppy usage...)

                        Probably a typo. No such thing as LSB, you probably meant lbs.

                        lbs is pounds. No conversion necessary.

                          The word pound and its abbreviation "lb" comes from latin words "libra pondo"
                          Where as what previous posts said that it is said when weighted scale is balanced. The abbreviation is used globally as "lb", whereas the pondo is used and translated to "pound" in US.

                          Later, the word "pound" is widely known and spread globally, but the abbreviation remain unchanged.

                              You may also like to know that it seems the word "Ounce" and its abbreviation "oz." comes from the Latin "Uncia", which was one twelfth of a Libra.
