Electromagnetic Equations Written in a Form Independent of the System of Units Available to Purchase

This paper illustrates a form for writing electromagnetic equations such that by substituting the appropriate value for each of two arbitrary constants one immediately obtains the electromagnetic equations written in any of the consistent systems of units. One constant is a dimensionless term called a rationalizing factor that takes the value $4π$ in unrationalized systems and unity in rationalized systems. The other is $ε0$⁠, the capacitivity of free space. Except for the rationalizing factor, all equations are identical in appearance with equations written in the rationalized MKSQ system of units. Maxwell's equations and some other commonly used relations are presented in this form. A simple method of obtaining the equations in the Gaussian and the Heaviside-Lorentz mixed systems of units from the form presented for consistent systems is also given.
