I previously had a similar question where I had to define my own unit that
may be helpful to you:

Boost Community,
I'm trying to create a custom velocity unit. I would like to create a unit that is in nautical miles per hour to represent my speed value. If I use pound_force.hpp as an example of units with more than one dimension I can create the following.
BOOST_UNITS_DEFINE_BASE_UNIT_WITH_CONVERSIONS(metric, nautical_mile_per_hour, "nautical mile per hour", "nmi h^-1", factor, si::velocity, ???);
If this is the right track, what id would I use and how do I know that it is unique?
This seems forced. I would rather define this unit in terms of meters

second. Nautical miles is already in terms of meters and hours is also defined as a scale of seconds. Can I somehow use these two already defined units to create the new unit? How would I do this?
You probably don't need to define a base unit. Just use:
typedef decltype( nautical_mile_base_unit::unit_type() / hour_base_unit::unit_type()) nautical_miles_per_hour;
