Possible changes to the International System of Units (SI) are being discussed, including a proposal to define the units by specifying the values of a set of fundamental constants. This note is meant to be an elementary guide to the algebra associated with unit exponents which can be used to both display the relationships between different sets of units and to provide simple tests of whether a particular set of constants provides combinations of units that form a complete set.
