      If I understood your question correctly, the pressure is always the force that you apply over an area.
      The mass of water that could be contained in you volume with 1ft height is almost 100 kg (if you correlate the volume with the density of water at normal conditions), if you multiply the mass for the gravitation acceleration g you get the force. Your area on which you apply this force is then one square inch, so if I didn’t make a mess with the conversions (I am not used to work with UK unit system), the pressure would be roughly 0.4 psi!
