International System of Units

$Reverse dependencies of the SI base units on seven [[physical constant]]s, which are assigned exact numerical values in the 2019 redefinition. Unlike in the previous definitions, the base units are all derived exclusively from constants of nature. Here, <math>a \rightarrow b</math> means that <math>a</math> is used to define <math>b</math>.$
