UnitSnapPounds per Square Inch to Kilopascals
1 psi = 6.894757 kPa
Kilopascals are the SI unit used on tire placards in Canada and Australia and throughout engineering standards, while many tools and gauges still read psi. Converting psi to kPa helps mechanics, students, and engineers report measurements in metric form or fill out documents that require SI units.
When you need to convert pounds per square inch to kilopascals
- Writing engineering or lab reports that require SI pressure units
- Matching a US-made gauge reading to a Canadian tire placard in kPa
- Converting HVAC refrigerant pressures for metric service charts
- Entering pressures into software or forms that only accept kPa
How to convert pounds per square inch to kilopascals
kPa = psi × 6.894757
Example: 5 psi = 34.47379 kPa
Common pressures in psi
| Pounds per Square Inch (psi) | Kilopascals (kPa) |
|---|---|
| 5 psi | 34.47379 kPa |
| 10 psi | 68.94757 kPa |
| 15 psi | 103.4214 kPa |
| 30 psi | 206.8427 kPa |
| 32 psi | 220.6322 kPa |
| 35 psi | 241.3165 kPa |
| 50 psi | 344.7379 kPa |
| 100 psi | 689.4757 kPa |
| 150 psi | 1,034.214 kPa |
Tips for converting pounds per square inch to kilopascals
- Multiply psi by roughly 6.9 to get kPa. Multiplying by 7 is faster and stays within about 2%.
- Since 100 kPa equals exactly 1 bar, a kPa result divided by 100 also gives bar.
- Keep track of whether a reading is gauge (psig) or absolute (psia); the conversion factor is the same, but the values differ by about one atmosphere.
