Bodyweight Moves Help

Every week I like to summarise the weights completed for the week. Part of this summary includes a weight distribution bias e.g. Legs, Shoulders, Arms, Chest.

Most exercises are easy to work out, I do squats and that total weight goes towards the leg category, I do bench press and that goes towards chest.

The problem comes when I am doing exercises that I cant use a weight for such as dips, pull ups etc. and theses are an important part of my training. My question is how would I work out the total weight put through the body? I can work my triceps just as hard for sets of 15 dips as I can work my legs doing 300lbs squats for 8 but calculating that is difficult and would like some advice.

Its not vital but is something I would like to be able to calculate.
