SI Base Quantities
International System (S.I.) Units
- There is a seemingly endless number of units in Physics
- These can all be reduced to seven base units from which every other unit can be derived
- These seven units are referred to as the SI Base Units; making up the system of measurement officially used in almost every country around the world

Six SI quantities are shown. The seventh quantity, the candela, measures luminous intensity, and is not covered in IB Physics. You may meet it later if you continue with Physics at university.
