Question
Describe briefly different types of systems of units.
✓
Answer
System of units are classified mainly into four types:
- C.G.S. system:
It stands for Centimetre-Gram-Second system. In this system, length, mass and time are measured in centimetre, gram and second respectively. - M.K.S. system:
It stands for Metre-Kilogram-Second system. In this system, length, mass and time are measured in metre, kilogram and second respectively. - F.P.S. system:
It stands for Foot-Pound-Second system. In this system, length, mass and time are measured in foot, pound and second respectively. - S.I. system:
It stands for System International. This system has replaced all other systems mentioned above. It has been internationally accepted and is being used all over world. As the SI units use decimal system, conversion within the system is very simple and convenient.
