Nowadays Maxwell's equations are formulated merely in the SI system. Physicists should also be familiar with other systems, like the systems of Gauss and Heaviside, but a comparison of equations in different systems is sometimes annoying. In a unified notation it is easier to switch from one system to another and to recognize the consequences of the chosen system. In covariant electrodynamics the comparison of the different systems is based on a frequently used representation of the
