1.5.10. Connection between Gaussian and SI units

| top | pdf |

Numerical values of magnetic quantities are given in the tables and figures in this chapter in Gaussian units together with information on how the corresponding values in SI units are obtained. As a summary, Table 1.5.10.1[link] gives for each such quantity the corresponding Gaussian unit and its value expressed in SI units. More details on the transformation between Gaussian and SI units are given e.g. in the Appendix of Jackson (1999[link]).
