Millinewton (mN)
The millinewton (symbol: mN) is a metric subunit of force in the International System of Units (SI), equal to one-thousandth of a newton (10⁻³ N). It is widely used in scientific research and precision engineering to measure very small mechanical interactions, such as surface tension forces, micro-electromechanical system (MEMS) actuation, and the delicate thrust produced by spacecraft ion thrusters. The unit provides a convenient scale for phenomena where standard newtons are too large to convey subtle force variations.
