Enter the muzzle energy and mass of the pellet into the calculator to determine the pellet velocity.

Pellet Velocity Formula

The following equation is used to calculate the Pellet Velocity.

PV = SQRT ( ME * 450240 / PW)
  • Where PV is the pellet velocity (ft/s)
  • ME is the muzzle energy (ft-lbs)
  • PW is the pellet weight (grains)

To calculate the pellet velocity, multiply the muzzle energy by 450240, then divide by the square root, and finally take the square root of the velocity.

What is a Pellet Velocity?


A pellet velocity describe the speed at which a pellet travels through the air when fired from a pellet-gun.

How to Calculate Pellet Velocity?

Example Problem:

The following example outlines the steps and information needed to calculate Pellet Velocity.

First, determine the muzzle energy. In this example, the muzzle energy is found to be 50 ft-lbs.

Next, determine the pellet weight. For this problem, the pellet weight is found to be 10 grains.

Finally, calculate the Pellet Velocity using the formula above:

PV = SQRT ( ME * 450240 / PW)

PV = SQRT ( 50 * 450240 / 10)

PV = 1500.39 ft/s
