When discussing buoyancy the first thing that comes to my mind is the tank. Charts abound for the buoyancy of various tanks, but what about the other stuff?

If one wants to be as precise as is possible with regard to buoyancy shouldn't the positive or negative buoyancy of every object worn or borne by the diver be calculated? To that end I ask this question:

What is a practical method for determining the buoyancy, positive or negative, of any object in pounds and ounces?
