What is Hydrostatic Pressure?
Hydrostatic pressure is the pressure exerted by a fluid at equilibrium due to the force of gravity. It increases linearly with depth in a fluid and depends on three key factors: the density of the fluid, the acceleration due to gravity, and the depth measured from the surface.
This pressure exists in both liquids and gases that are subject to gravity. In everyday scenarios, we experience hydrostatic pressure when swimming underwater, in blood pressure measurements, or in industrial applications like dam construction and submarine design.
How to Calculate Hydrostatic Pressure
Step 1
Select the fluid type from the dropdown menu. Choose between fresh water, salt water, or enter a custom fluid density if you’re working with a different liquid.
Step 2
Choose your calculation method – either converting from depth to pressure or pressure to depth.
Step 3
Enter your known value (either depth or pressure) in your preferred units. The calculator supports multiple unit conversions including meters, feet, Pascals, and atmospheres.
Step 4
Review the results, which will show both the calculated pressure and corresponding depth. The calculator automatically applies the hydrostatic pressure formula P = ρgh, where ρ is fluid density, g is gravitational acceleration (9.81 m/s²), and h is depth.
Step 5
Examine the detailed explanation provided below the results, which shows the exact values used in the calculation and helps verify the accuracy of your results.
