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.

Kilopascal

kPa

The kilopascal equals 1000 pascals. Used for tyre pressures in many metric countries, engineering pressures and weather reports. 100 kPa ≈ 1 bar ≈ atmospheric pressure.

Real-world: Tyre pressure: 220–280 kPa. Atmospheric: 101 kPa. HVAC duct static: 0.1–0.3 kPa.

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.
