UnitSnapKilopascals to Pounds per Square Inch
1 kPa = 0.1450377 psi
Vehicles sold in Canada, Australia, and other metric markets often list recommended tire pressure in kPa, yet many air pumps and gauges are labeled in psi. Converting kPa to psi lets drivers inflate correctly and helps anyone reading metric specifications on equipment marked in imperial units.
When you need to convert kilopascals to pounds per square inch
- Inflating tires to a placard value given in kPa using a psi gauge
- Interpreting weather or altitude pressure data for a US audience
- Translating metric pressure ratings on pipes, hoses, or valves
- Reading imported appliance or pump manuals that use kPa
How to convert kilopascals to pounds per square inch
psi = kPa × 0.1450377
Example: 5 kPa = 0.7251887 psi
Common pressures in kPa
| Kilopascals (kPa) | Pounds per Square Inch (psi) |
|---|---|
| 100 kPa | 14.50377 psi |
| 180 kPa | 26.10679 psi |
| 200 kPa | 29.00755 psi |
| 220 kPa | 31.9083 psi |
| 240 kPa | 34.80906 psi |
| 250 kPa | 36.25943 psi |
| 300 kPa | 43.51132 psi |
| 500 kPa | 72.51887 psi |
| 1,000 kPa | 145.0377 psi |
Tips for converting kilopascals to pounds per square inch
- Divide kPa by roughly 6.9, or multiply by about 0.145, to get psi.
- Typical car tire placards in kPa read somewhere around 200 to 250, which lands in the low-to-mid 30s in psi.
- Standard atmospheric pressure is 101.325 kPa, so a reading near 100 kPa may be absolute pressure rather than a gauge value.
