The kilonewton is a multiple of the unit bit for Force. The prefix kilo (symbol k) is defined in the International System of Units (SI) as a multiplier of 10 × 102 (1 thousand, short scale), and therefore 1 kilonewton = 10 × 102 newtons = 1000 newtons. The kilonewton has the unit symbol kN.

The newton (symbol: N) is the International System of Units (SI) derived unit of force. It is named after Isaac Newton in recognition of his work on classical mechanics, specifically Newton's second law of motion.
