How to convert FPS to MPH

Just in case you're wondering how fast your bullet (or arrow) is moving in terms that damned near anybody can understand I've gone to the trouble of looking up the formula for you.
No thanks necessary, I was curious myself.

Multiply feet per second by 0.68181818.

5280 feet in a mile
3600 seconds in an hour
3600 / 5280 = 0.68181818
or 45 / 66 = 0.68181818
