In Ancient Latin times the unit of measurement, the pound, was not as it is considered today. Today a contemporary, or modern day pound is ~453.592g. This was established by the US & other other members of The Commonwealth of Nations on July 1, 1959. Whereas, in Roman times, when Latin was still used as a means of communication by any society or group of peoples, it was ~327.168g. These units of measure were called a "libra".
Hope that helps.
