Joule and Velocity Calculator
Use this calculator to calculate the muzzle velocity (FPS and m/s) and energy (Joules) for your airsoft gun or air rifle. You can enter the pellet/bb weight in grams, as well as either the energy in joules or the muzzle velocity in FPS or m/s, and the calculator will automatically compute the other values. To use the calculator:
- Enter the weight of your pellets or BBs in grams (e.g., 0.20 for airsoft BBs or 0.80 for air rifle pellets).
- Enter either the energy in joules, the velocity in FPS (feet per second), or the velocity in m/s (meters per second), depending on what you know.
- Click "Calculate Muzzle Velocity" and the calculator will display both the velocity in m/s and FPS as well as the energy in joules.

How does a joule and velocity calculator work?
This calculator allows you to easily convert between energy (joules), velocity in meters per second (m/s), and velocity in feet per second (FPS). For airsoft players and airgun owners, it is essential to know both muzzle velocity and energy to ensure that the guns comply with safety regulations.
How is energy calculated in joules?
Energy in joules is calculated using the weight of the pellet or BB and the velocity of your projectile. The formula for calculating energy is:
Joules = 0.5 * pellet weight (kg) * velocity² (m/s)
With this calculator, you can quickly and easily input your pellet or BB weight and either velocity or energy, and the other values will automatically be calculated.
Why is it important to know muzzle velocity?
Muzzle velocity is crucial for both precision and safety when using an airsoft gun or air rifle. If your gun has too high a muzzle velocity, it can exceed safety limits at shooting ranges or airsoft fields. It is important to regularly test your gun to ensure it complies with the allowed limits. Use this calculator to ensure that your muzzle velocity and energy are at the correct levels.
