Enter the bullet weight (grains) and the velocity (fps) into the Power Factor Calculator. The calculator will evaluate the Power Factor.
- Bullet Energy Calculator
- Projectile Energy Calculator
- Muzzle Pressure Calculator
- Muzzle Velocity Calculator
Power Factor Formula
The following two example problems outline the steps and information needed to calculate the Power Factor.
PF = W * V / 1000
Variables:
- PF is the Power Factor ((gr-fps))
- W is the bullet weight (grains)
- V is the velocity (fps)
How to Calculate Power Factor?
The following steps outline how to calculate the Power Factor.
- First, determine the bullet weight (grains).
- Next, determine the velocity (fps).
- Next, gather the formula from above = PF = W * V / 1000.
- Finally, calculate the Power Factor.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
the bullet weight (grains) = 125
velocity (fps) = 1000
PF = W * V / 1000 = ?
