# Muzzle Energy Calculator

Muzzle energy is the kinetic energy of the bullet when expelled out from the muzzle to the target. Muzzle energy will be higher when bullet is heavier and moves out faster from the muzzle. It is calculated from mass, velocity and weight of the bullet. Use this online calculator and find the muzzle energy in foot pounds and joules.

Muzzle energy is the kinetic energy of the bullet when expelled out from the muzzle to the target. Muzzle energy will be higher when bullet is heavier and moves out faster from the muzzle. It is calculated from mass, velocity and weight of the bullet. Use this online calculator and find the muzzle energy in foot pounds and joules.

#### Formula:

Energy (foot-pounds) = (Bullet Weight x Velocity2) / 450240 Energy (Joules) = Energy (foot-pounds) x 1.35581795

#### Example

A bullet has a weight of 150 grams and travels at a velocity of 1500 fps. What is the muzzle energy in ft-lbs and joules.
Energy (foot-pounds) = (150 x 1500x1500) / 450240
= 337500000 / 450240
= 749.6002 ft-lbs
Energy in Joules = 749.6002 x 1.35581795
=1016.3214 Joules.
