Subject: [Boost-users] [units] Creating a velocity unit

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 per
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?
