How to fill it
Fill the inputs. The tool shows the outputs.
On the tool screen, Calc is the working sheet. Presets stores values you reuse. Reference is the formula, assumptions, and provenance below.

Diagnose
This tool does not attach diagnose observations.
Assumptions
- Uniform density. Atmospheric pressure is not added — result is gauge.
Provenance
- Hydrostatics. Signed height yields signed gauge pressure.
