About PSI and Pascal

The pound per square inch is about 6,894.757 pascals. US tire pressures, water systems, and industrial equipment are rated in psi. The pascal is the SI derived unit of pressure: one newton per square meter. It is small for everyday pressures, so kilopascals and hectopascals appear more often in practice. One PSI equals 6894.757293 Pascals (1 psi = 6894.757293 Pa). PSI is used in US tire pressure and in US plumbing and well systems. Pascal is used in physics and engineering calculations.

Precision and Rounding:Several pressure factors are exact by definition (1 atm = 101,325 Pa; 1 bar = 100,000 Pa) while others, like psi and mmHg, are derived and carry long decimals. Tire and weather readings tolerate whole-number rounding; calibration, medicine, and process engineering need the full factor before rounding.

Use the pressure conversion guide to compare mmHg, mbar, inHg, kPa, Pa, and torr across medical, weather, aviation, vacuum, and engineering work.

Conversion factors per NIST Special Publication 811 and the BIPM SI Brochure (9th edition) (reference).
