Answer 1

You have to remember fundamental units of Length, Mass, Time, Electric Current, Thermodynamic Temperature, Amount of substance and Luminous Intensity, which are Metre, Kilogram, Second, Ampere, Kelvin, Mole and Candela respectively...........

They will be the SI units as well as the MKS unit......

CGS is the smaller degrees of that.....like meter to centimeter.....kilogram to gram etc....

FPS is foot-pound-system which is not too important here in India ok it is for the Britishers.......
