      Mass or weight is the measure  of heaviness of an object.  It can be measured  by
                         different types of scales.

                        The standard units of mass or weight are milligram, gram and kilogram. 1 kg = 1000 g.
                        We use gram (g) to weigh lighter objects and kilogram (kg) to weigh heavier objects.
