@jonnyboy: It's simply dividing kinetic energy by barrel volume - hardly fancy maths. It basically gives you an idea of how powerful a cannon is for its size, but it's not really a number of a huge amount of worth.
Well it will at least give you a ball park estimate of what other cannons your is similar to.
