SI has explicitly distinct units for mass (the kilogram) and force (the newton). Numerous older units of pressure, energy, and power are superseded by the pascal, the joule, and the watt, respectively. Each equation defining a derived unit contains only the number 1 as the numerical factor...
Mass of an object is defined as the amount of matter that is present in the given object. The SI unit of mass is kilogram. To learn more about the si unit for mass and other units, visit BYJU'S.
