What is a millinewton?

A millinewton (mN) is an SI unit of force equal to one thousandth of a newton, representing the force needed to accelerate a 1 gram mass at 1 m/s².

What does gram-force measure?

Gram-force (gf) is a non-SI force unit defined by the force exerted by a one gram mass under standard gravity (9.80665 m/s²).

Why convert millinewton to gram-force?

This conversion helps translate precise SI force values into practical units often used in tactile switch actuation, spring rating, and engineering product testing.
