How it works
Estimate the pressure increase below a fluid surface. Atmospheric or other surface pressure must be added separately for absolute pressure.
Inputs and units
| Input | Example value | What to enter |
|---|---|---|
| Fluid density | 1,000 kg/m³ | Required unit: kg/m³. Use a non-negative value. |
| Depth | 10 m | Required unit: m. Use a non-negative value. |
| Gravity | 9.80665 m/s² | Required unit: m/s². Must be greater than zero. |
Worked example

This example is generated by the same calculation engine using the starting values in the form. Your own inputs produce your own result.
- Fluid density
- 1,000 kg/m³
- Depth
- 10 m
- Gravity
- 9.80665 m/s²
Complete example results
- Pressure increase
- 98,066.5 Pa
Reading the result
Check the units used in the formula together. The result follows the stated ideal model and supplied constants; material, environment and losses are included only where the inputs or method explicitly define them.
Questions and answers
Can I use the example values for my own calculation?
The example values illustrate the calculation. Replace every input with your own information, especially dates, rates and the selected operation.
Why are some results rounded?
Results display up to 8 decimal places. Calculations use the unrounded values; very small values use scientific notation. JavaScript floating-point arithmetic can introduce tiny rounding differences.
Are my inputs sent to a server?
The calculator processes inputs in your browser. Its code does not send your values to a server.
