Editing Avogadro constant (section)

== Connection to other constants ==
The Avogadro constant {{math|''N''{{sub|A}}}} is related to other physical constants and properties.
* It relates the [[molar gas constant]] {{mvar|R}} and the [[Boltzmann constant]] {{math|''k''{{sub|B}}}}, which in the SI is defined to be exactly {{val|1.380649|e=−23|u=J/K}}:<ref name=NIST2019/>

* It relates the [[Faraday constant]] {{mvar|F}} and the [[elementary charge]] {{mvar|e}}, which in the SI is defined as exactly {{val|1.602176634|e=−19|u=[[coulomb]]s}}:<ref name=NIST2019/>
