Some [common units](systems_of_units.md#common-units) expressed with a specialization of the
`common_unit` class template need special printing rules for their symbols. As they represent
a minimum set of common units resulting from the addition or subtraction of multiple quantities,
we print all of them as a scaled version of the source unit. For example the following:
