Hi, I posted before about having a problem with having so many units that it takes forever to install. I was thinking about trying to perhaps dynamically create only the ones I need, because I can't know that at compile-time. Mostly it would be scaled units. For instance I might have the unit meter, but might want to create a scaled unit, say like kilometer or millimeter. Also though I wouldn't mind being able to create some of the astronomical units when necessary, such as parsec or light year. But in all cases, the base units already exist. What would be the best way to do this?
