not sure what you mean...
Pressure in pascals can be found by P = F / A where F is force (in newtons) and A is area (in square meters). If you're after the ideal gas law, it's PV=nRT. Is this what you're looking for?

There's a bazillion equation for pressure. Only one is its definition, though,
P=-dU/dV _ S
Hard to write in ascii. Pressure P is defined as minus the partial derivative of energy U with reference to volume V, holding entropy S constant.

Or from water it would be 0.43333psi per foot of depth.
(62.4pounds/1ft^3) (1ft^2/144in^2) = 0.433333 psi / ft
