@ DannyB: The unit is pounds per square inch. The more square inches you have, the more pounds you need to generate the same PSI.

Force radiates away from clamp in a 45 degree angle. The point of a caul is to increase the surface area over which a single caul is able to apply force. They don’t multiply the force, they divide it. Take a look at the diagram below to see what I mean.
