particular, all of the following quantities are dimensionally equivalent in Gaussian units, but they are nevertheless given different unit names as follows: General rules to translate a formula Any formula can be converted between Gaussian and SI units by using the symbolic conversion factors from Table 1 above. For example, the electric field of a stationary point charge has the ISQ formula where r is distance, and the "I" superscript indicates that the electric field and charge are defined as in the ISQ. If we want the formula to instead use the Gaussian definitions of electric field and charge, we look up how these are related using Table 1, which says: Therefore, after substituting and simplifying, we get the Gaussian-system formula: which is the correct Gaussian-system formula, as mentioned in a previous section. For convenience, the table below has a compilation of the symbolic conversion factors from Table 1. To convert any formula from Gaussian system to the ISQ using this table, replace each symbol in the Gaussian column by the corresponding expression in the SI column (vice versa to convert the other way). This will reproduce any of the specific formulas given in the list above, such as Maxwell's equations, as well as any other formula not listed. For some examples of how to use this table, see: Once all occurrences of the product have been replaced by , there should be no remaining quantities in the equation that have an ISQ electromagnetic dimension (or, equivalently, that have an SI electromagnetic unit).
