Why Is Water Potential Measured In Units Of Pressure? [Solved]

Water potential is equal to DPD or Diffusion Pressure Deficit in terms of the magnitude and opposite to it in terms of the sign. Since DPD is measured in the unit of pressure like pascals and atm as it is a type of pressure, so water potential is also measured in terms of pressure units like pascals and atmospheres.
