About both units

From

Pound per Square Inch

psi

Pounds per square inch equals approximately 6895 Pa. It is the dominant pressure unit in the US — tyre pressures, plumbing, compressed air. Standard US tyre pressure: 32–35 psi.

Real-world: US tyre: 32–35 psi. Water supply: 40–60 psi. SCUBA tank: 3000 psi. Car AC system: 30–200 psi.

Pascal

The pascal is the SI unit of pressure — one newton per square metre. Named after Blaise Pascal. 1 Pa is a very small pressure; atmospheric pressure is about 101,325 Pa. Pressure readings in engineering are usually in kPa or MPa.

Real-world: Atmospheric pressure: 101,325 Pa. Conversation level: 0.001 Pa sound pressure. Truck tyre: 900,000 Pa.

Tips & common mistakes

Quick tips

1 psi ≈ 6.9 kPa = 0.069 bar.
14.7 psi = 1 atm = 1.01 bar.
Most US pressure gauges show psi.

Avoid these

Setting a European tyre at 35 bar instead of 35 psi — disaster.
Confusing psi (gauge) with psia (absolute).
Using psi in scientific papers — prefer Pa or MPa.
