Practical A.E.G Upgrade 2006

BTW, the formula for calculating Joules uses MPS (meters per second) rather

than FPS as the unit for representing velocity - as you know, the US uses non-SI

(Système Internationale) units such as feet, gallons and miles, while most other

parts of the world use SI units such as meters, liters and kilometers. To translate

FPS into Joule, you will need to first convert FPS to MPS. The conversion rate is

(roughly) 3.28, so you may do the math accordingly:

where E= the impact energy in Joules; m= the mass in kilograms, which is the

weight of the bullet; and Vx= velocity in MPS.

FPS - MPS conversion:

1 m/s = 3.281 ft/s

1 ft/s = 0.3048 m/s

If you don’t want to do the calculation by hand, refer to the following online

calculator for help:

In fact, this calculator offers functions for calculating the effective range and the

drop distance of a bullet. You will, however, likely see different results in the real

world (due to the many different outdoor conditions and the

sometimes-unpredictable back-spinning effect created by the hopup function).
