The first time I ever heard the word "fortnight" was when somebody told me that one furlong per fortnight is almost exactly 1 cm per minute.
That was also the first time I was exposed to the word "furlong". You can imagine my confusion.

Do we still do this in intro physics courses? I still remember this one from ~30 years ago. (Physicist hazing ritual?)

@lewriley Fortunately I managed to go through all of my undergraduate and PhD without ever touching the Imperial unit system.

@j_bertolotti @lewriley Those games work outside the imperial system as well: a megameter per second is almost exactly a milliparsec per year, for example (perfectly normal astronomical units)
