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.
millinewtons
The millinewton is a multiple of the unit bit for Force. The prefix milli (symbol m) is defined in the International System of Units (SI) as a multiplier of 1 × 10-3 (1 thousandth, short scale), and therefore 1 millinewton = 1 × 10-3 newtons = 0.001 newtons. The millinewton has the unit symbol mN.
