1 psi = 6894.76 Pa (pound per square inch → pascal)
1 psi = 6894.76 Pa
1 pound per square inch equals 6894.76 pascals. To convert pounds per square inch to pascals, multiply the pound per square inch value by 6894.76. For quick reference: 1 psi = 6894.76 Pa, 5 psi = 34473.8 Pa, 10 psi = 68947.6 Pa, 100 psi = 689476 Pa.
Pascals = Pounds per square inch × 6894.76PSI to pascals multiplies by 6,894.757 (1 psi = 6,894.757293168361 Pa exactly). A 32 psi tyre is 220,632 Pa; a 3,000 psi pressure-washer rating is about 20.7 million Pa. The conversion carries US automotive, plumbing, and hydraulic specs into base SI units for engineering calculations. Check whether the source figure is gauge or absolute: US gauges read psig, pressure above atmospheric, so an absolute-pressure formula needs roughly 101,325 Pa added before the physics comes out right.
Process-control engineers specifying fine differential-pressure transmitters work in pascals for the sensor's native resolution, even when the surrounding plant is rated in psi. A tiny 0.1 psi differential — enough to trigger a filter-change alarm — is 689.5 Pa; a 5 psi low-pressure gas line is 34,474 Pa. Because psi is a coarse unit at this scale, HVAC and cleanroom instrumentation almost always reports natively in pascals, and cross-checking a psi-labelled nameplate against a pascal sensor needs the precise 6,894.757 factor to avoid a tenfold misread.

Most US passenger-car tires call for 32–35 psi. A typical bicycle tire runs 50–80 psi. In pascals, that gives you: 1 psi = 6894.76 Pa, 10 psi = 68947.6 Pa, 100 psi = 689476 Pa.
The pound per square inch (psi) is the customary US pressure unit, derived from the avoirdupois pound-force on a square inch (≈ 6,894.76 Pa exactly). It is the standard unit on US car tire-pressure stickers, scuba gauges in the US, and most plumbing specifications.
The pascal (Pa) is the SI derived unit of pressure, defined as one newton per square meter. It is the universal unit in physics and engineering documentation. In everyday life pascals are tiny — atmospheric pressure is around 101,000 Pa — so multiples like kPa and MPa dominate practical use.
