Fundamental and Derived Units F.P.S, C.G.S, M.K.S and SI Units
By Anand | 12:55 AM MST, Thu January 01, 2026
- F.P.S system is the British system in which the basic units of length, mass and time are foot, pound and second respectively.
- C.G.S system is the metric system in which the basic units of length, mass and time are centimeter, gram and seconds respectively.
- M.K.S system is another metric system in which the basic units of length, mass and time are metre, kilogram and second respectively
- S.I. units are referred to as Systems International units which is again of metric and the basic units, their names and symbols are as follows.
