A kilogram is the SI base unit of mass, equal to 1,000 grams or approximately 2.205 pounds. Originally defined in 1795 as the mass of one liter of water, the kilogram was fixed by a platinum-iridium cylinder from 1889 until 2019, when it was redefined in terms of the Planck constant. It is the only SI base unit whose name carries a prefix.
