Airgun CalculatorsHandy tools to convert velocity to energy and back again! |
Calculate Energy:Enter the velocity of your rifle in feet per second, and the weight of your pellet in grains to calculate the energy of your airgun at the tested range. |
Calculate Velocity:Enter the known energy level of the airgun in foot pounds, along with the pellet weight in grains to calculate the velocity in feet per second. |
If the forms above do not run on your computer, you can always calculate these figures manually.
Energy is calculated as follows:
Velocity (fps) * Velocity (fps) * Pellet Weight (grains) / 450240 = Energy (ft/lbs)
Velocity is calculated as follows:
The square root of (Energy (ft/lbs) * 450240 / Pellet Weight (grains)) = Velocity (fps)
