Etymology
Noun
kilogram (plural kilograms)
In the International System of Units, the base unit of mass; conceived of as the mass of one litre of water, but now defined by taking the fixed numerical value of the Planck constant h to be 6.626 070 15 × 10-34 when expressed in units of kg⋅m2⋅s−1. Symbol: kg
(proscribed) 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.)
• Whilst one kilogram equals 1,000 grams, it is the kilogram and not the gram that is the base unit.
Synonyms
• kilo
• kg
