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? quantitysi::length test_m = 1.0 * meter; quantityus::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
