Multiplication of physical quantities creates new units. When you calculate the area, the unit becomes multiplied by itself to become, m2. The unit of area is an example of a derived unit. Other derived units occur so often they are named after illustrious scientists, in honour of their work.

This Table  list derived units and their special names.
