We propose to introduce two new electromagnetic unit systems

in place of the Gauss unit system

to be used in conjunction with the rationalized MKS unit system. They are both CGS systems called CGSE system and CGSM system respectively

and therefore they are both as convenient for dealing with theoretical problems as the Gauss system

and yet

when expressed in them

the Maxwell equations

etc.

take on the same form as when the rationalized MKS system is used

if suitable values for ε0 andμ0 are adopted. This is indeed quite an advantage. Derivations are given to clarify the points.
