Kilogram is the primary unit of mass in the SI system. Kilo is a prefix meaning 1000 and is part of official SI nomenclature. Itâs intended to be applied to SI units such as meters, grams and Hz. It would be perfectly appropriate to apply it to other SI units such as kelvins, seconds and so on, although thatâs less frequent.
