Those physical quantities are which are calculated from fundamental unit is called derived unit. Like as :- Velocity= Displacement/Time ; Velocity depend on displacement and time.
All except basic unit are derived units.
These unit can be expressed in terms of all fundamental units.
| Derived Quantities | Derived Units |
| Area | length*width = m*m =m2 |
| Density | mass/volume = kg/m3 |
| Work | force*displacement = joule |
| Moment | mass*velocity = kg-m/s |
| Force | mass*acceleration = newton |
