About PSI and Kilopascal
The pound per square inch is about 6,894.757 pascals. US tire pressures, water systems, and industrial equipment are rated in psi. The kilopascal is 1,000 pascals. Tire pressures in metric countries, weather systems, and engineering specs commonly use kilopascals. One PSI equals 6.894757293 Kilopascal (1 psi = 6.894757293 kPa). PSI to Kilopascal conversion comes up most often in US tire pressure and in US plumbing and well systems, typically when figures need restating for tire pressure in metric countries.
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.
Conversion factors per NIST Special Publication 811 and the BIPM SI Brochure (9th edition) (reference).
