Mass units as units of weight | Measurement | Physics

The use of mass units (Kg) to measure weight is not scientifically accurate, but it has become common usage. Scientifically, mass is the amount of matter present in an object and it only changes if we add matter to or remove matter from the object. Weight is the force that a body feels in the presence of gravity, therefore weight changes depending on the gravitation of the location. For example, the weight of an object on the moon is 6 times lower than its weight on earth but it has the same mass in both locations. In common usage it has become acceptable to use weight when we actually mean mass since the acceleration due to gravity is the same everywhere on Earth, but remember that this is not accurate.
