Here's a fun one to try...
units -v lightyear "light year"
Confused? Try "units -v" on each of the terms individually, and the results might be enlightening, albeit a bit time-consuming. (Sorry, I couldn't resist.)
Astronomy geeks might want to browse the units.dat file (RTFM), to find out just how many ways you can define a year! :P
And speaking of RTFM, +1 for units as a future RTFM topic.

So you can also compute how many feet light travels in a nanosecond (Try it; you can remember the answer with less than 2% error).
RIP Grace Hopper! (Look it up if you're too young to remember.)

And once again, I learn something new from the master Adam. I'z immediately "yum install units" I think units(1) might make a good RTFM? Especially going over some of it's esoteric units (i.e. millilightseconds? really?). Or have we done units and I just can't remember? === Bradford C.
