Foot Pounds of Energy Calculator
The Foot Pounds of Energy (FPE) Calculator is a tool used to calculate the amount of energy produced by a projectile or object in foot-pounds.
Formula
The formula used to calculate FPE is:
FPE = (Mass x Velocity^2) / 450240
Where:
- Mass is the weight of the object in pounds.
- Velocity is the speed of the object in feet per second.
Example
If a projectile has a mass of 150 grains (approximately 0.02177 pounds) and a velocity of 1000 feet per second, the calculation would be: FPE = (0.02177 x 1000^2) / 450240 = 0.0482 foot-pounds of energy.
Therefore, the projectile would produce approximately 0.0482 foot-pounds of energy.
