Centinewton is an SI unit of force equal to one-hundredth of a newton (0.01N). A single newton is defined as force that accelerates an object with the mass of one kilogram one meter per second each second. The centinewton is a popular unit of measurement commonly used in the keyboard space for actuation force readings - for example, IBM's membrane buckling springs actuation force range can be expressed as 64-69cN. Compared to the other popular unit for actuation force gram-force, 1cN is equal to 1.02gf.
