GENERAL KNOWLEDGE

Detailed explanation-1: -The SI unit of mass is the kilogram (kg). In science and technology, the weight of a body in a particular reference frame is defined as the force that gives the body an acceleration equal to the local acceleration of free fall in that reference frame.

Detailed explanation-2: -Mass (weight) Units. The Metric System of Measurements uses the mass units: gram (g), kilogram (kg) and tonne (t). 1000 g = 1 kg. 1000 kg = 1 tonne.

Detailed explanation-3: -The units of mass in the metric system have the same prefixes as the units of length: 1 Kilogram (kg) = 1000 grams (g) 1 hectogram (hg) = 100 g. 1 decagram (dag) = 10g. 1 gram (g) = 1 g.

Detailed explanation-4: -The kilogram, symbol kg, is the SI unit of mass. It is defined by taking the fixed numerical value of the Planck constant h to be 6.626 070 15 x 10–34 when expressed in the unit J s, which is equal to kg m2 s–1, where the metre and the second are defined in terms of c and Cs.

Detailed explanation-5: -The kilogram (also kilogramme) is the unit of mass in the International System of Units (SI), having the unit symbol kg. It is a widely used measure in science, engineering and commerce worldwide, and is often simply called a kilo colloquially. It means ‘one thousand grams’.
