What this calculator does
Pressure is force per area. In fluids it increases with depth.
Formula and method
P = F ÷ A; hydrostatic P = ρ g h (+ 101,325 Pa for absolute pressure at sea level)
Worked example
Calculated by this tool with its default inputs:
Inputs
- Calculate: Pressure from force and area

How to read the results
About every 10 m of water adds one atmosphere.
Assumptions and limitations
- Incompressible fluid assumed.
These are educational estimates. Electrical, structural and other safety-critical work must comply with local codes and be designed or checked by a qualified professional.
Questions
Gauge vs absolute?
Gauge pressure is relative to the atmosphere; absolute includes it.
