A unit is defined as the standard of reference chosen to measure any physical quantity. The SI unit is the abbreviation used for System International d’ units. It was introduced by the General Conference of the Weights and Measure, France, in \(1960\). ...
Mass is a measure of how much material is in an object, but weight is a measure of the gravitational force exerted on that material in a gravitational field. Despite the terms being used interchangeably in everyday usage, these two concepts are not equivalent and have units of kg and N, ...
