Table of Electromagnetic Quantities and Their Units

The table below lists quantities that appear in the equations of natural law related to electromagnetic phenomena. For each, the table includes the typical formulaic symbol for the quantity, the conventional terminology used to refer to it, in some cases alternative terminology which Primel introduces, along with the coherent unit provided by SI, the coherent unit (quantitel) provided by Primel, and the conversion from the Primel unit to SI units.
