What is the SI unit for force?

Explanation:
Force is measured in newtons. A newton is the force that gives a mass of one kilogram an acceleration of one meter per second squared, so 1 N equals 1 kg·m/s^2. This links directly to F = ma. The other units represent different quantities: a joule is energy or work (1 J = 1 N·m), a watt is power (1 W = 1 J/s), and a pascal is pressure (1 Pa = 1 N/m^2).
