The formula is:
FPE = W x V^2 / 450240
FPE is energy in ft. lb.
W is pellet weight in grains
V is velocity in ft./sec. (squared in the formula)

The real question is "How is FPE relevant?"
The answer: It tells you how powerful your gun is.
FPS on the other hand just tells you how fast it shoots the projectile. Which is meaningless in and of itself.
FPE is the number that you should focus on when it comes to gauging your rifle's potency. FPS is what you focus on when it comes to consistency. |

His AGH dossier indicated that he has double 0 top secret clearance, so Dussalater is O.K.
By the way, Broom: Your dossier includes a Groningen police file from July 23, 2004 at 0126 GMT. Something about a pecadillo involving a Swedish flight attendant, a railroad locomotive, and a box of cornflakes. Did you ever get that resolved?
Dussalater - peruse the main page at your leisure. There's a lot of good stuff there. The glossary is a good place to start:
