What are the fundamental units in Physics?

 As we know that there are many units of a system but we use SI unit frequently because they are the important (use in majority of time) or fundamental unit of that system.

There are 7 important fundamental quantities :

1. Length = meter (m)

1. Mass = Kilogram (kg)

1. Time = Second (s)

1. Current = Amphere (A)

1. Thermodynamic Temperature = Kelvin (k)

1. Amount of Substance = Mole (mol)

1. Luminious Intensity = Candela (cd)
