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 basic SI units are kelvin, candela, metre, kilogram, mole, ampere, and second. Units can be combined, leading to derived units that are used to describe more complex properties. Examples of derived units are velocity and acceleration. Frequently Asked Questions about Units Physics What are SI units? SI units are the basic units used today.
