Ammo damage calculation

I’ve been working on a mod to add more ammo to the game. I was looking though the 50 cal section when I noticed that the MK 211 has a note of the ammo having an effective range of 20m and 65kj equaling 225 power. Does anyone know how this number was made? I can’t make any equation that is consistent.

Thank you, I didn’t think about finding the square root.
