WebbIn the 2024 revision of the SI, the definitions of four of the SI base units – the kilogram, the ampere, the kelvin and the mole – were changed. Their new definitions are based on fixed numerical values of the Planck constant ( h ), the elementary charge ( e ), the Boltzmann constant ( k ), and the Avogadro constant ( NA ), respectively. WebbThe SI unit for luminous intensity is the candela [2] which has an operational definition. This means it is defined by a set wavelength of light emitting a specific amount of power.
