When you need to convert pound per square inch to kilopascal
Pressure conversions are used for tyre inflation, weather readings, scuba and industrial gauges, and HVAC work, where gauges and manuals may be calibrated in different units.
Vehicle tyre placards and industrial gauges often list both kilopascals and psi.
Typical values: 0.5 psi is about 3.4474 kPa, and 100 psi works out to roughly 689.4757 kPa. Because the ratio is fixed at 6.8948, you can scale any amount linearly — doubling the psi doubles the kilopascals.
A single tyre or gauge spec is often printed in two or three pressure units side by side for international use.
How to convert pound per square inch to kilopascal
One pound per square inch equals 6.8948 kilopascals. To convert, multiply the number of psi by 6.8948:
kilopascals = psi × 6.8948
For example, 10 psi × 6.8948 = 68.9476 kilopascals.
