Units developers/user,

I need some help understanding unit conversions using boost::units. I see there are conversions.hpp header files. Does this mean that there are built-in unit conversions for fundamental units, or even mainstream derived ones by simply including the conversions and performing the appropriate operation?

Can I do something like this, for instance?

quantity<si::length> test_m = 1.0 * meter;
quantity<us::inch> test_in = test_m * inch / meter;

What is the best way to go about setting up conversions, or for that matter, defining a unit system; for instance, the us (english) unit system does not appear to be available?

I've read a couple of the old mailing list entries, but I'm not sure I fully understand the examples that I could follow them.

Thank you...

Regards,

Michael
