Definition of Pound: The pound (shortened to lb. or lbs.) is used to measure an object’s mass. In everyday use, it is also for measuring an object’s weight. There have been different types of pounds throughout history. The one used in the US and other countries for weighing is the international avoirdupois pound.

In countries that use the metric system, the kilogram is used instead of pounds for determining an object’s weight. 1 kilogram is the same as 2.2046 avoirdupois pounds.
