Following are the fundamental quantities along with their units in the SI system :

1. Length – The basic unit of length in the SI system is the meter (m).
2. Mass – For mass, the SI unit is the kilogram (kg).
3. Time – Time is measured in seconds (s).
4. Electric Current – The unit for electric current is the ampere (A).
5. Thermodynamic Temperature – Temperature in the SI system is measured in kelvin (K).
6. Amount of Substance – The unit used is the mole (mol).
7. Luminous Intensity – This is measured in candela (cd).

These seven fundamental quantities and their SI units are the foundation of measurement in science and technology. A clear understanding of them is essential for accurate and standardized measurements across various fields.
