How to Calculate Pressure
What is Pressure?
Pressure is force applied per unit area (P = F/A). Higher pressure results from more force on the same area, or the same force on a smaller area. It appears in tyres, weather systems, hydraulics, and medicine.
Step-by-Step Guide
- 1P = F / A (Pressure = Force / Area)
- 2SI unit: Pascal (Pa) = N/m²
- 31 atm = 101,325 Pa = 14.696 psi
Worked Examples
Input
Force 500 N · Area 0.25 m²
Result
P = 500/0.25 = 2,000 Pa = 2 kPa
