Muzzle Velocity Calculator

Find muzzle velocity from a projectile's kinetic energy and mass.

Calculated Output

Muzzle velocity 632.46

Formula: v = √(2·KE ÷ m)

Step-by-Step Breakdown

1. Values used:

2. Kinetic energy = 1,800 J

3. Projectile mass = 9

5. Muzzle velocity = 632.46

Did this calculator solve your problem today?

The math behind it

From kinetic energy KE = ½mv², the speed is v = √(2·KE ÷ m).

1800 J on a 9 g bullet → about 632 m/s.

Why convert grams to kg?

SI energy in joules needs mass in kilograms for the formula to balance.
