I am having trouble converting from one derived_dimension to another across systems (imperial to metric). I'd like to convert, say, lb/in to, say, kg/m. I thought I would do the following but get a compiler error #:
It's not going to work. lb is a unit of force, but kg is a unit of mass. They are not compatible and there is no conversion between them.

units are not dimensions. You can't use derived_dimension with base_units.
