Hydrostatic Pressure Calculator

Choose which quantity to calculate. The others become inputs.
Gauge pressure ignores the atmosphere above the fluid surface. Absolute adds 1 atm (101.325 kPa) on top.

At 10.00 m depth, the gauge pressure is 97.8900 kPa.

  • Absolute pressure (including 1 atm at the surface) is 199.2150 kPa.
  • In this fluid (998 kg/m³), pressure rises by 97.890 kPa for every 10 m of depth.
  • This depth is within the recreational scuba open-water limit (0-18 m).
  • Hydrostatic pressure depends only on depth and fluid density - the shape or volume of the container does not matter (Pascal's hydrostatic paradox).

Next stepFor pressurized systems, add the working pressure of any pump or compressor to the hydrostatic component to find total system pressure.
