___ 1: Avoirdupois units are officially units of mass. However, in commercial and everyday use, weight is a synonym for mass. The pound avoirdupois (lb) has only one legal definition in the United States: "1 pound (avoirdupois) = 0.453 592 37 kilogram" (National Institute of Standards and Technology). The pound force (lbf) used in science is not the pound avoirdupois (lb); it does not belong to the avoirdupois system: it is not a unit of mass but a unit of force.
