What is 220 kPa in PSI?

220 × 0.145038 ≈ 31.9 PSI — a common tire pressure.

What is 100 kPa in PSI?

100 × 0.145038 ≈ 14.5 PSI — nearly one standard atmosphere.

Why do Canadian tire specs use kPa?

Canada uses the metric system, so tire pressure is labeled in kPa. US tires use PSI. Always use the placard inside your door as the authoritative reference.

Kilopascals to PSI Converter

Convert kilopascals to PSI when reading Canadian or Australian tire specs, pressure relief valve ratings, or international engineering documentation in US equipment contexts.

Formula

Multiply kilopascals by 0.145038 to get PSI. To reverse, divide PSI by 0.145038 to get kPa.

About these units

Kilopascal

The kilopascal is the SI pressure unit at a practical scale, used in automotive specifications in Canada, Australia, and many other metric countries. One kPa equals 1000 Pa or approximately 0.145 PSI.

Pound per Square Inch

PSI is the dominant pressure unit in US automotive, industrial, and consumer contexts. American tire inflators, pressure relief valves, and gas cylinders are rated in PSI.
