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.
kilonewtons
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.
