Depends on why you want to know. If you are just trying to get an estimate of the cost of a project I'd use your soil testing data to estimate the thickness assuming that the thickness need to be about equal to the spread needed to develop the soil bearing necessary to support weight. And that depends on the soil bearing capacity.
If you're getting ready to pour concrete you've gotten ahead of yourself. I'd hire a structural engineer to design the foundations and bearing plates for the legs. Saves you money in the long run, they can adjust the strength and reinforcement used in the concrete to give you the most economical design.

Do your own homework. If this truly is your own project and each leg really was supporting 12000 # then you would definitely be able to figure how thick the concrete should be. Plus you need steel also.

it depends what type of soil under concrete pad
then how wide is footing

just this data not sufficent
