There are seven SI base units.
Refer to the related link below for a table of the seven SI base units.
Base quantities are the quantities on the basis of which other quantities are expressed. The quantities that are expressed in terms of base quantaties are called derived quantities.
All other quantities which described in terms of base quantities are called base quantities.
Physical Quantities are of TWO types: 1) Fundamental Quantities. 2) Derived Quantities.
