Question

Question :- Define System of Different Units Briefly.

Answer 1

Answer :-

★ System of Units :- A complete set of units which is used to measure all kinds of fundamental and derived quantities is called a system of units.

» Some commonly used systems of units are as follows :-

i) cgs system - It was set up in France. It is based on centimetre, gram and second as the fundamental units of length, mass and time respectively.

ii) fps system - It is a British system based on foot, pound and second as the fundamental units of length, mass and time respectively.

iii) mks system - It is also a French system based on metre, kilogram and second as the fundamental units of length, mass and time respectively.

iv) SI : The International System of Units - SI system is the abbreviation for "Systeme Internationale d' Unites", which is French equivalent for international system of units. It is modernised and extended and extended form of the metric systems like cgs and mks systems. This system was adopted by eleventh General Conference of Weights and Measures in 1960. It covers all branches of science and technology.

★ More to know :-

• Basic SI quantities and units :

✒ Length = metre (m)

✒ Mass = kilogram (kg)

✒ Time = second (s)

✒ Temperature = kelvin (K)

✒ Electric Current = ampere (A)

✒ Quantity of matter = mole (mol)

✒ Luminous Intensity = candela (cd)

• Supplementary SI units are :-

✒ Plane Angle = radian (rad)

✒ Solid Angle = steradian (sr)

Answer 2

Explanation:

:- Define System of Different Units Briefly. - Brainly.in A system of units is a set of related units that are used for calculations. ... For example, in the MKS system, the base units are the meter, kilogram, and second, which represent the base dimensions of length, mass, and time, respectively. In this system, the unit of speed is the meter per second.
