Excel Joule Converter
 

I just made a joule converter in Excel.

I was always calculating it long hand from the BB weight and the FPS so, I decided to make this for my BlackBerry and I wanted to share with those who wanted it.

Joule Converter

For those curious, the calculation is this,

FOR FPS
.5 * (BB WEIGHT / 1000 kilograms) * (FPS * .3048 MPS) ^2

FOR MPS
.5 * (BB WEIGHT / 1000 kilograms) * MPS ^2

Thanks for your time, have a good day.

Or you could just do a quick google search to find one online.
There's about 5 programs you can download as well, and probably a few apps.

or just print a chart... put it in your gun case.

For chrono purposes; I write a list of maximum fps per BB weight on my chrono
Realistically, you really don't need to know what specific muzzle energy their gun is shooting, you only need to know if it's under the limit.

FPS Calculator alternative + Joules Chart
 

Found this really good Joules/FPS calculator too (use it all the time when configuring my guns)

Also includes a joules chart that you can use to check if your gun's output is safe/legal.

Hope this helps
