What is pressure?
Pressure is force applied per unit area. The SI unit is the pascal (Pa), equal to one newton per square meter (N/m²).
FormulaPa = N / m²
Key conversions
- 1 bar = 100,000 Pa = 100 kPa
- 1 atmosphere (atm) = 101,325 Pa ≈ 1.01325 bar
- 1 psi (pound per square inch) ≈ 6,894.76 Pa
- 1 kPa ≈ 0.145038 psi
