p = F/A

Pressure from force and area

Small contact areas create high pressure for the same force.

MINTSI
01

Inputs

Force per area; distinguish gauge from absolute fluid pressure.

Force normal to the area.

Actually loaded area.

02

Result

Select a target and calculate.

Calculation

p = F / A

Small contact areas create high pressure for the same force.

Understand the inputs
  • Mean pressure pForce per area; distinguish gauge from absolute fluid pressure.
  • Normal force FForce normal to the area.
  • Effective area AActually loaded area.
Example

1,000 N over 100 cm² gives 1 bar.

Assumptions and limits

Uniformly distributed static normal load.
