Fundamental Quantities in Physics
In physics, fundamental quantities are the basic physical quantities that are independent of each other and serve as the foundation for measuring all other physical quantities. These quantities cannot be derived from any other quantity. The International System of Units (SI) defines seven fundamental quantities, each with a unique unit and symbol.
| Fundamental Quantity | SI Unit | Symbol of Unit |
|---|---|---|
| Length | metre | m |
| Mass | kilogram | kg |
| Time | second | s |
| Electric current | ampere | A |
| Temperature | kelvin | K |
| Amount of substance | mole | mol |
| Luminous intensity | candela | cd |
