Find the velocity feet per second of the exiting pellet.
Pellet weights and energy calculator.
Obtain multiple velocities from different gun settings or any other combination you want to compare with our fpe calculator to calculate muzzle energy.
Bullet kinetic energy calculator.
Simple add the speed and grains into each of the boxes for each column.
Pellets of various calibers are available in flat nose round nose pointed and hollow point configurations.
Muzzle energy is the kinetic energy of the bullet when expelled out from the muzzle to the target.
Muzzle energy is the energy calculated right when the projectile just leaves the gun barrel at the muzzle.
Find the foot pounts of energy of the exiting pellet.
After the pellet leaves the barrel wind resistance starts to slow its speed.
The square root of that number is your velocity.
That would be 11 37 times 450240 and divide that number by 8.
Then hit the square root key on your calculator.
It may be out of date.
Let s find the velocity of an 8 grain pellet that generates 11 37 foot pounds of energy.
Muzzle energy will be higher when bullet is heavier and moves out faster from the muzzle.
Feet per second fps ballistic coefficient.
In order to determine the kinetic energy you must know the velocity of the bullet and the weight of the bullet in grains.
Use the calculator below to calculate the kinetic energy of a bullet.
It may be inaccurate.
Calculated from retained velocity at two distances.
Use this online calculator and find the muzzle energy in foot pounds and joules.
Pellets are generally wasp waisted cylinders made of lead or non lead alloys and provide the highest accuracy in the rifled barrels of adult precision air rifles and air pistols.
You may add items to the list on the right in order to create a bar graph comparing the different items.
Foot pounds of energy from a pellet or rifle is easily calculated with the speed of the projectile and the weight in grains.
This page was the most popular page so i have left it available online for historical reference.
I have moved on to other hobbies.
This airgun energy calculator is a simple widget designed to take the velocity of a projectile bb pellet dart or bullet its weight in grains and calculate the foot pounds of energy fpe at the muzzle.
Take the energy times the constant 450240 and divide by the weight of the pellet in grains.
Velocity from muzzle energy.
