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.
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.
