See 
https://www.boost.org/doc/libs/1_70_0/doc/html/boost_units/Dimensional_Analysis.html 
and https://www.boost.org/doc/libs/1_70_0/doc/html/boost_units/Units.html.

If you're not interested in any conversions, then you can simply define 
a new system containing a single new dimension and new base unit.  These 
will happily coexist with other systems and units, as long as you never 
try to mix values from the two.

Things get more complicated if you want to perform conversions from 
other units, however.
