Muzzle Velocity Calculator
Find muzzle velocity from a projectile's kinetic energy and mass.
Muzzle velocity is a projectile's speed as it leaves the barrel.
The math behind it
From kinetic energy KE = ½mv², the speed is v = √(2·KE ÷ m).
Worked example
1800 J on a 9 g bullet → about 632 m/s.
FAQ
Why convert grams to kg?
SI energy in joules needs mass in kilograms for the formula to balance.
