About This Calculator
This Airgun Energy Calculator helps you estimate the muzzle energy of your airgun by calculating the foot-pound (ft-lb) energy based on pellet weight and velocity. It's a useful tool for airgun shooters to check power output and ensure legal or competition compliance.
How It Works
- Enter the pellet weight in grains (gr).
- Enter the velocity in feet per second (ft/s).
- Click "Calculate" to get the energy result in foot-pounds (ft-lb).
The energy is calculated using this standard formula:
Energy =
Pellet Weight × Velocity²

Frequently Asked Questions
What units should I use for this calculator?
Pellet weight must be entered in grains (gr) and velocity in feet per second (ft/s).
Why is the result shown in foot-pounds?
Foot-pounds (ft-lb) is the standard energy unit for measuring airgun muzzle energy in shooting sports and specifications.
Can I use this for other types of projectiles?
This tool is optimized for airgun pellets. For bullets or firearms, use a dedicated bullet energy calculator to ensure accuracy.
