Formula
kilopascals = psi × 6.89476
Pressure is force per area. 1 atm = 101.325 kPa = 14.696 psi = 760 mmHg. Bar is a metric working unit close to atmospheric pressure (1 bar = 100 kPa).
About Psi and Kilopascals
Psi (psi): Pounds-force per square inch, the customary US pressure unit; 1 psi = 6,894.76 Pa. Common uses: US tire pressure (car tires typically 30-35 psi), US gas grills (10-12 psi propane), industrial hydraulics in the US, and US plumbing pressure specifications.
Kilopascals (kPa): A thousand pascals; the practical SI pressure unit for atmospheric and engineering work. Common uses: Weather reports (atmospheric pressure in kPa, where standard sea-level pressure is about 101 kPa), tire pressure in many countries, and structural engineering.
How the conversion works
Pressure is force per area. 1 atm = 101.325 kPa = 14.696 psi = 760 mmHg. Bar is a metric working unit close to atmospheric pressure (1 bar = 100 kPa).
The exact relationship is kilopascals = psi × 6.89476, which the calculator at the top of this page applies in both directions. Type into either field and the other updates immediately.
When this conversion matters
Converting between psi and kilopascals comes up wherever pressure measurements move between systems — from one country's conventions to another's, from a scientific reference to a practical specification, or from one industry's working unit to another's. The calculator and reference table above cover the everyday range; for unusual values you can type any number into either field.
