They are used to measure quantities that are not basic.
Length, for example, is a basic unit, but area and volume are not so derived units will be used to measure area and volume.
The SI unit of voltage is the Volt, which is a derived unit equivalent to a Joule/Coulomb.

The Newton is the SI derived unit for force.
Derived Unit
The recommended unit is kilometer (derived from the SI unit meter).
Liter because it's the base unit of volume
It is measured in gradient which is measured in the metric system!
The coulomb is an SI derived unit used to measure electric charge. It is a special name given to an 'ampere second', which are both SI base units.
derived
The unit used for measure temperature is the kelvin
The Watt is the unit used to measure electric power :)
It is a measure of mass per unit volume and is derived using measures of mass and lengths in three orthogonal dimensions.
