Fluid Pressure Calculator

0.0(0)

Calculates fluid pressure using the formula P = ρgh (density * gravity * depth) or based on force and area (P = F/A).

How To Use

How to use this calculator

Start with your values, or try a preset.

Step 1

Enter Fluid Density (ρ), Depth (h), Acceleration due to Gravity (g), Force (F), and Area (A) in the units shown.

Step 2

Read Pressure (due to force/area) and Pressure (due to depth) in the results panel. Results update as you change the inputs.

Step 3

Choose a preset to load an example, then adjust the values for your situation.
