Pascals to PSI Converter
Convert pascals to pounds per square inch — one psi is 6,894.76 Pa, so pascals run large. Results update as you type; exact factors shown.
One pascal is 0.0001 pounds per square inch — see the exact factor, not a rounded rule of thumb.
How the pascals to psi converter works
Pressures convert through the pascal (1 N/m²). One bar is exactly 100 kPa; a standard atmosphere is exactly 101.325 kPa; 1 psi is 6.894757 kPa (a pound-force on a square inch); 1 mmHg is 133.322 Pa by the conventional definition.
Australia is fully metric under the National Measurement Act 1960; imperial units appear only in trade with the US and in older documents.

FAQFrequently asked questions about pressure conversion
How many pascals in one psi?
6,894.757 Pa.
What is 100,000 Pa in psi?
14.50 psi — just under one atmosphere.
Why use pascals at all?
It is the SI unit, so it drops straight into physics and engineering equations without a conversion factor.
What is 1000 Pa in psi?
0.145 psi.
Are kilopascals more practical?
Usually yes — everyday pressures are thousands of pascals, which is why gauges are marked in kPa.
