And Trey Harris's "500 mile email" story is what clued me on to GNU units and its capabilities.
Reminder: if you're on MacOS, or one of the BSDs, your default units is from BSD, not the GNU version, and is far less capable. GNU units can be installed on MacOS through Homebrew. The package is "gnu-units", the command is "gunits" once installed.
GNU Units is also available in FreeBSD ports, just type "pkg install units" (or go to /usr/ports/math/units and "make install"). It likewise gets the binary name "gunits"
