P=\frac{F}{A}Variables
- P: pressure
- F: perpendicular force
- A: area
How to use this formula
Calculates average pressure as perpendicular force divided by the area receiving that force.
Important notes
- The SI unit is the pascal, equal to one newton per square metre.
- Use the normal component of force.
Quick example
A 100 N force spread over 0.5 m² produces 200 Pa.
Applicability, worked calculation, and verification
Assumptions and domain checks
- The SI unit is the pascal, equal to one newton per square metre.
- For the Pressure Formula, every denominator must be nonzero, and the numerator and denominator must remain correctly grouped.
- Use dimensionally consistent units and the sign, coordinate, and reference-frame conventions stated for the problem.
Worked example
A 100 N force spread over 0.5 m² produces 200 Pa.
Common mistakes
- When copying Pressure Formula, keep the complete numerator and denominator grouped; a missing brace or parenthesis changes the result.
- Verify the result of Pressure Formula with a known case, inverse operation, dimensional check, or independent calculation before publishing it.
