How to use it
- Enter depth in meters.
- Review or adjust seawater density.
- Calculate pressure units.
Seawater Pressure Calculator
Estimate ideal hydrostatic gauge pressure at an entered seawater depth.
Important: This calculator is an educational estimate only. It is not marine navigation, voyage planning, vessel, diving, rescue, flood, storm, coastal, offshore, pressure-vessel, engineering, legal, or safety advice.
About the Seawater Pressure Calculator
Convert a vertical seawater depth into ideal hydrostatic gauge pressure.
Formula
Gauge pressure equals seawater density times gravitational acceleration times depth.
Example
Ten meters at 1,025 kg/m³ gives about 100.52 kPa gauge pressure.
Notes
Atmospheric pressure, waves, motion and equipment limits are excluded; this is not diving or pressure-vessel guidance.
