Fundamental Quantities and their Units

Fundamental quantities are basic physical quantities that cannot be expressed in terms of other physical quantities. They are independent. The following are the seven fundamental quantities and their SI units:

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)

Derived Quantities and their Units

Derived quantities are physical quantities that are expressed as combinations of fundamental quantities. Their units are derived from the fundamental units. The following are some examples of derived quantities and their SI units:

Area – square metre (m²)
Volume – cubic metre (m³)
Density – kilogram per cubic metre (kg/m³)
Speed/Velocity – metre per second (m/s)
Acceleration – metre per second squared (m/s²)
Force – Newton (N) or kilogram metre per second squared (kg m/s²)
Pressure – Pascal (Pa) or Newton per square metre (N/m²)
Energy/Work – Joule (J) or Newton metre (Nm)
