The SI unit used to express force is called what?

Explanation:
Force is measured in newtons. A newton is defined as the force that gives a mass of one kilogram an acceleration of one meter per second squared, so F = m × a and 1 N = 1 kg·m/s^2. Other units shown correspond to different quantities: joule is energy, watt is power, and pascal is pressure. So the SI unit for force is the newton.
