Pressure Calculator
Calculate pressure from force and area using P = F/A. Convert between pressure units (Pa, atm, PSI, bar).
Enter any two values to find the third.
Enter two values.
Pressure Formula
P = F / A
Pressure is force per unit area. 1 Pascal = 1 N/m².
Example: 100 N over 0.5 m²
P = 100 / 0.5 = 200 Pa
P = 100 / 0.5 = 200 Pa
