WebWithout using the Earth as a reference body, the surface gravity may also be calculated directly from Newton's law of universal gravitation, which gives the formula. … WebAs we have seen, the base SI unit of mass is the kilogram (kg), but metric prefixes need to be applied to the gram (g), because we are not allowed to “double-up” prefixes. Thus, a thousand kilograms (10 3 kg) is written as a megagram (1 Mg) since. 103kg = 103 × 103g = 106g =1Mg. 10 3 kg = 10 3 × 10 3 g = 10 6 g = 1 Mg.
