Define mass. State its (i) S.I. (ii) C.G.S and (iii) F.P.S units. How are they related?
Answer
The mass of a body is the quantity of matter contained in it.
(i) S.I. Unit — Kilogram (kg)
(ii) C.G.S unit — Gram (g)
(iii) F.P.S unit — Pound (lb)
Relationship between kilogram, gram and pound
1 kg = 1000 g = 2.20462 lb,
1 g = 10-3 kg = 2.20462 10-3 lb
1 lb = 453.59 g = 0.45359 kg
