English: Metrological dependencies between the different base units of the proposed redefinition of the SI system of units as it currently stands, including the fundamental constants used to define them:

- the frequency of some to-be-determined optical transition for the second, 
- the speed of light for the metre,
- the Planck constant for the kilogram,
- the Avogadro constant for the mole,
- the sensitivity of the human eye for the candela,
- the Boltzmann constant for the kelvin, and
- the elementary electric charge for the ampere.
