3 Οκτ 2024 · Calculation Formula. The formula to calculate Foot Pounds of Energy (FPE) is given by: \[ E = \frac{M(g) \times BS^2}{450,437} \] where: \(E\) is the Foot Pounds of Energy (ft-lbs), \(M\) is the mass of the bullet in grains, \(BS\) is the bullet speed in feet per minute (ft/min).
Have you ever wanted to compare a fast lightweight bullet to a slower heavy bullet to see which one hits harder? Just enter your bullet weight below and its velocity. This calculator will display the foot pounds of energy, and help you compare the power of different loads.
Our Foot Pounds of Energy Calculator allows you to easily calculate this energy, ensuring you have the data you need for making informed decisions about ammunition and performance. Formula. The formula used to calculate foot pounds of energy is: Energy (E) = (Mass in Grains (M) * Bullet Speed (BS)²) / 450437. Where:
30 Ιουλ 2024 · To calculate a bullet's energy in foot-pounds, follow these steps: Multiply the bullet's velocity (v) in foot per second by itself to obtain the velocity squared. Multiply this result with the bullet's mass (m) in grains. Divide this result by 450436.686 to obtain the bullet's energy (E) in foot-pounds: E = (m ⋅ v²)/450436.686 ft-lbs
15 Αυγ 2024 · Enter the mass in grains and the bullet speed into the calculator to determine the Foot Pounds of Energy.
15 Αυγ 2024 · The following formula is used to calculate the foot-pounds energy (FPE) of a projectile. To calculate FPE, square the project velocity, multiply the result by the weight in grains, then divide by 450240. FPE is short for foot-pounds of energy. This term is used to describe the kinetic energy contained in a projectile.
3 Οκτ 2024 · The formula for calculating foot-pounds of energy (FPE) is given by: \ [ \text {FPE} = \frac {V^2 \times W} {450240} \] where: \ (W\) is the weight of the projectile in grains. If a projectile has a velocity of 3000 ft/s and a weight of 100 grains, its FPE can be calculated as follows:
