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.

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.
