The differences between Fundamental units and Derived units are mentioned in the table below:Fundamental UnitsDerived UnitsFundamental units are the units of fundamental physical quantities. There are only seven fundamental units in the SI system.Derived units are the units of derived physical quantities. There are hundreds of derived units in the SI system.They have their own identity and can be defined independently.They do not have their own identity and depend upon the fundamental units for definition.Example: kilogram (kg), meter (m), second (s), etc.Example: Joule (J), Newton (N), Pascal (Pa), etc.
