Popular pressure conversions
PSI to Bar1 psi = 0.0689476 bar. Standard atmosphere = 14.696 psi ≈ 1.013 bar. Car tires run at 30–35 psi.Bar to PSI1 bar = 14.5038 psi. Standard atmosphere = 1.01325 bar. Car tires are typically 2.0–2.5 bar (29–36 psi).Kilopascals to PSI1 kPa = 0.145038 psi. Atmospheric pressure = 101.325 kPa = 14.696 psi. Car tires: 207–248 kPa.PSI to Kilopascals1 psi = 6.89476 kPa. Atmospheric pressure = 14.696 psi = 101.325 kPa. Tire pressure: 30–36 psi.Megapascals to PSI1 MPa = 145.038 psi. Used for concrete strength (20–50 MPa), hydraulic systems, and steel yield stress.Atmospheres to Bar1 atm = 1.01325 bar — the international standard atmosphere. Equivalent to 14.696 psi = 101.325 kPa.

What is pressure?
Pressure is force applied per unit area.
Common use cases
- Tire pressure
- Fluid and gas systems
- Industrial gauges
- Weather and meteorology
- Medical (blood pressure)
Ambiguity notes
PSI can mean gauge (psig) or absolute (psia). Context determines which.
