How many quantity are there in fundamental quantity?

the differentiate between fundamental quantity and derived quantity?

Fundamental quantities are such things as the kilogram ( a physical mass of metal), the Metre (now defined by reference to atomic oscillations). [In detail, metre, second, kg, mole, Kelvin, candela.]...

Fundamental quantities are those which do not depend on other quantities. (i.e. temperature, mass, length) Derived quantities are those which depend on fundamental quantities. (i.e. force, volume,...

Area, volume, density , speed/velocity , acceleration , force , work done.   Area= length x breadth = m x m = 2m (meter square) Volume= length x breadth x height = m x m x m = 3m (meter cube)...

The quantity which has only direction is called fundamental quantity.Example-Direct current.The quantity which has both magnitude and direction is called derived quantity.Example-Altranating current.
