A derived unit is a unit of measurement in the International System of Units (SI) that is derived from one or more of the seven base units.

Examples of derived units:

• Velocity (m/s)
• Density kg/m3
• Force (Newton)
• Pressure (Pascal)
• Energy (Joule)
• Power (Watt)

We can derive other units from the independent units. The independent units are called Fundamental Units (or Base Units).

Examples of fundamental units are Mass in kilogram (kg); Electric Current, ampere (A); Temperature, kelvin (K); Amount of Substance, mole (Mol).
