Progress of the SI and CGS Systems: Conversion of the MKSA Units to the MKS and CGS Units

摘要

Recording of the equations in mechanics does not depend on the choice of system of measurement. However, in electrodynamics the dimension of the electromagnetic quantities (involving current, charge and so on) depends on the choice of unit systems, such as SI (MKSA), CGSE, CGSM, Gaussian system. We show that the units of the MKSA system can be written in the units of the MKS system and in conforming units of the CGS system. This conversion allows to unify the formulas for the laws of electromagnetism in SI and CGS. Using the conversion of units we received two new formulas that complement Maxwell's equations and allow deeper to understand the nature of electromagnetic phenomena, in particular, the mechanism of propagation of electromagnetic waves.
