My biggest issue is that my recent software development experience has involved using Java much more than C++ and I'm trying to learn how to use a C++ library that makes pretty heavy use of templates.

The examples directory has simple, functional demonstrations of just about every type of functionality that anyone has wanted to date.
Okay, I've looked at the code related to conversions. conversion_factor.cpp sets up a bunch of double values that I assume are used to convert values in one unit to values in another. However, they aren't used in any code.
- Does the library provide functions for converting between different units? ... for example, converting from miles to kilometers. If not, is there a recommended way to do this?
Dimensionally consistent quantities can be converted by explicit construction or through conversion_factor. See the examples I listed earlier.
I don't see any example that actually performs a conversion using conversion_factor. Can you show me how to use that to convert miles to kilometers? It looks like kilometers isn't defined in any of the .hpp files. I can just multiply meters by 1000 myself, but if there's something in the library that hides this detail, I'd like to know about it. --- Mark Volkmann
