Mass - kilogram (kg)
- a coherent body of matter with no definite shape.

Time - second (s)
- the indefinite continued progress of existence and events.

Electric current - ampere (A)
- flow of electric charge.

Thermodynamic temperature - kelvin (K)
- A measure proportional to the thermal energy of a given body at equilibrium.

Amount of substance - mole (mol)
- the number of specified group of entities present in a substance.

Luminous intensity - candela (cd)
- an expression of the amount of light power emanating from a point source within a solid angle of one steradian.
