Aug 5, 2023 · The Formula. The formula for calculating Foot Pounds of Energy is relatively straightforward: E = (1/2) x mass x (velocity*2) Where: E represents the Foot Pounds of Energy. mass is the mass of the object in pounds. velocity is the velocity of the object in feet per second. Using the Calculator.
Bullet Energy Calculator. 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. Bullet Weight.
6 days ago · 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
- How do you calculate bullet energy at 100 yards?A bullet may lose anywhere between 20-30% of its velocity by the first 100 yards. To accurately calculate the bullet energy at 100 yards, you must...
- What is the muzzle energy of a .338 Lapua Magnum at 3000 ft/s?A .338 Lapua Magnum round with a bullet weight of 250 grains will have a bullet energy of 4995 ft-lbs (6773 J) at 3000 ft/s. To arrive at this answ...
- How does barrel length affect muzzle velocity?If everything else remains the same, a longer barrel length will allow the propellant gas to act on the bullet longer, thus accelerating it to high...
6 days ago · 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).
1 foot pound-force per second is equivalent to: 1.3558179483314 watts; 1.8 18 × 10 −3 horsepower; Related conversions: 1 watt ≈ 44.253 728 96 ft⋅lbf/min = 0.737 562 149 333 ft⋅lbf/s; 1 horsepower (mechanical) = 33,000 ft⋅lbf/min = 550 ft⋅lbf/s; See also. Conversion of units; Pound-foot (torque) Poundal; Slug (unit) Units of energy ...
Now add the values into the above-listed formula and multiply the velocity square by the weight. After that divide it with the constant and you will have the results in Foot Pounds of Energy. Our online foot pounds energy calculator also requires these two values to perform the calculations accurately. So you must have the correct values. Example:
Aug 21, 2023 · Understanding FPE (Foot-Pounds of Energy) And Muzzle Energy Formula. The formula for calculating muzzle energy is as follows: E = (M x V²) ÷ K. The well-known formula, muzzle energy = 0.5 * Mass * Velocity^2, elegantly captures the relationship between a projectile’s mass and velocity at the moment it exits the muzzle.
