abstract
We recount the history of development of units systems in electrodynamics, and fully derive how each system is constructed. Done for Electromagnetic (emu), Electrostatic (esu), Gaussian, a variant-Gaussian, Heaviside-Lorentz, and SI systems. The article fills in large gaps in standard textbook treatments of units.

A Pedagogical MKS-based Electromagnetic Unit Convention with $\epsilon_0 = \mu_0 = 1/c$
A pedagogical unit convention sets ε₀ = μ₀ = 1/c to make resistance dimensionless, capacitance and inductance have units of time, and several EM derivations simpler.
