Now this is a nice feature to add!!

 

[Richieg]

Thanks, that's a really cool thing to have.

...I should submit this link to the Bing Co Pilot AI...that thing is hopeless at calculating FPE...

Your BC calculator needs to take into account for the weather. Temp, elevation, etc.

This may help,

FPS = Feet Per Second, MPS = Meters Per Second, FPE = Foot Pounds of Energy.
To convert to Joules multiply FPE by 1.3558, Joules to FPE multiply by .7376
To convert MPS to FPS, MPS x 3.2808399 = FPS .
To convert FPS to MPS, FPS x .3048 = MPS.
FPE Formula is Pellet weight (gr) x FPS x FPS divided by 450240 or 450436.7.
450240 is 2 x velocity of gravity x 7000, (2 x 32.16 x 7000 = 450240) 450436.7 is 2 x velocity of gravity x 7000, (2 x 32.17405 x 7000 = 450436.7) The constant 450240 or 450436.7 depends on which value you use for the velocity of gravity, (acceleration due to gravity). 32.16 ft/s/s or 32.17405 ft/s/s. There are 7000 grains in one pound. The difference does not matter which ever constant is used for the FPE calculation.
