kilogram

kilogram

The kilogram (kg) is the base unit of mass in the SI system of units. The standard kilogram is a 1 kg corrosion resistant platinum/iridium cylinder, carefully preserved in the suburbs of Paris (with a backup copy kept in Gaithersburg, Maryland.) Efforts are underway to replace these artifacts by redefining the kilogram as the mass of a certain number of silicon atoms.
