Finally, on top of all this, in both CGS-ESU and CGS-EMU as well as in the Gaussian system, Maxwell's equations are ‘unrationalized', meaning that they contain various factors of that many workers found awkward. So yet another system was developed to rectify that: the ‘rationalized’ Gaussian system, usually called the Lorentz–Heaviside system. This system is still used in some subfields of physics. However, the units in that system are related to Gaussian units by factors of , which means that their magnitudes remained, like those of the Gaussian units, either far too large or far too small for practical applications.
