The SI was previously defined in terms of seven base units and derived units defined as products of powers of the base units. The seven base units were chosen for historical reasons, and were, by convention, regarded as dimensionally independent: the metre, the kilogram, the second, the ampere, the kelvin, the mole, and the candela.


From 20 May, the SI units will be defined in terms of constants of nature, in which: the unperturbed ground state hyperfine transition frequency of the caesium-133 atom Δ ν is 9 192 631 770 hertz, also the speed of light in vacuum c is exactly 299 792 458 metres per second the Planck constant h

It is a matter of choice how many and which quantities are considered base quantities. 9 SI has chosen the seven base quantities The 7 SI base units in the above table can be used to derive all other SI units called SI derived units. For example the SI unit of speed is the SI derived unit using two base units meter and second, that is meters per second (m/s). SI units definition: an international system of measurements that is based on particular metric units, including metres….

The International System of Units (abbreviated SI from the French Le Système International d'Unités) is the modern form of the metric system and is generally a system devised around the convenience of the number ten. It is the world's most widely used system of units, both in everyday commerce and in science.
