FPE calc
Find the foot-pounts of energy of the exiting pellet
Pellet Weight: Grain
Velocity: FPS


Foot-Pounds of Energy (FPE)


Joules
FPS calc
Find the velocity, feet per second, of the exiting pellet
Energy: FPE
Pellet Weight: Grain


Feet Per Second (FPS)
Ballistic coefficient
Calculated from retained velocity at two distances
Nearest Distance: Yards
Farthest Distance: Yards
Velocity at Near Distance: FPS
Velocity at Far Distance: FPS


Ballistic Coefficient
Retained velocity
See how much velocity is retained at point of impact
Muzzle Velocity: FPS
Range to Target: Yards
Ballistic Coefficient:


Retained FPS
Tank Fill calc
Determine how many fills you can get with your airgun

Convert Pressure

=

Tank Capacity cu. ft.
Tank Pressure psi
Fill Airgun To This Pressure psi
Refill Airgun At This Pressure psi
Airgun Cylinder Has This Volume cc
Carbon fiber tank vs. a standard scuba tank

to standard 3000 psi 80 cu. ft. tank...

Times!
*Note...a negative number means the standard tank cannot fill even once!
