About the units
Pascal (Pa)
The pascal is the SI unit of pressure, one newton per square meter.
PSI (psi)
Pounds per square inch is the US unit for tire, air compressor and hydraulic pressure.
How to use this converter

- See the same value in every other pressure unit just below.
- Use “Swap units” to convert PSI back to pascals.
When you’ll use the pascal to psi conversion
Converting pascals to psi comes up more often than you might expect — for example when checking blood pressure units, scuba and diving calculations, or inflating tires to the right pressure. Type your number once and you get the exact answer plus every related unit, so you don’t need to convert twice.
💡 For a quick estimate in your head, multiply by about 0.00015 (the exact factor is 0.00014503773773).
Watch out for these mix-ups
- Gauge pressure ignores atmospheric pressure; absolute pressure includes it.
- Mixing psi and bar on tire labels — 2.2 bar is about 32 psi.
Tips for better results
- Double-check which system a unit belongs to (for example US vs UK gallons).
- Use the swap button to convert in the opposite direction instantly.
- Bookmark the conversions you use most — each pair has its own page.
