One Furlong per Moment is Equal to Five Miles per Hour.
Yesterday I was bored at work when I got the idea to try and come up with my own unit for measuring speed. I have always found the furlong per fortnight pretty amusing but it is absolutely unusable. I get that that's the point, but still having a unit in the same vein that is still usable in daily life would be fun.
So after some quick googling I found that in medieval Europe a solar hour (1/12 of a solar day) was divided into 40 parts. One 40th of a solar hour is a "Moment". So after running the numbers with a coworker, we found that one Fur/Mom is about 2.235 m/s. Given that, it turns out that 2.235 m/s is nearly exactly 5 (4.9995) mph
All this is to say, I will be rejecting all units both imperial and metric for this obviously superior system.
