## kilogram

Noun

- (proscribed)
*Hence,*the unit of weight such that a one-kilogram mass is also a one-kilogram weight.

Usage notes

- (proscribed, unit of weight): The use of the kilogram as a unit of weight is somewhat imprecise, as weight can change while mass remains constant. The weight of a one-kilogram mass will depend on its location, because the pull of gravity varies from one place to another. It is therefore frequently proscribed, but is nonetheless in wide use (e.g., a person's weight in kilograms). (The same imprecision and proscription also occur with many other words pertaining to weight and mass, such as the verb
*weigh*.)
