How to convert Kilopascals to PSI
To convert kilopascals to psi, multiply by 0.145038. One kilopascal equals 0.145038 psi, and one psi equals 6.894757 kPa.
- Take the value in kilopascals — for example 7.5 kPa.
- Multiply by 0.145038 (the number of psi in one kilopascal).
- 7.5 × 0.145038 = 1.087783 psi.
Quick mental estimate: Divide the number of kilopascals by 6.9 (within 0.1% of the exact answer).

About converting Kilopascals to PSI
Kilopascals (kPa) and PSI (psi) are both units of pressure. The exact factor is 1 kPa = 0.145038 psi, so multiply by 0.145038 to go from kilopascals to psi (or divide to go back).

Real-world pressure in kilopascals and psi
| Example | Kilopascals | PSI |
|---|---|---|
| A systolic blood pressure of 120 mmHg | 15.9987 kPa | 2.320415 psi |
| A pressure cooker's over-pressure (15 psi) | 103.4214 kPa | 15 psi |
| The standard atmosphere | 101.325 kPa | 14.69595 psi |
| A typical car tyre (32 psi) | 220.6322 kPa | 32 psi |
| An espresso machine (9 bar) | 900 kPa | 130.534 psi |
| A road-bike tyre (90 psi) | 620.5282 kPa | 90 psi |
| A scuba cylinder (200 bar) | 20,000 kPa | 2,900.755 psi |

The units
1,000 pascals.
Used for: Tyre pressure in Canada/Australia, weather and engineering.
Pounds-force per square inch, about 6,894.757 Pa.
Used for: US tyre pressure, air compressors and hydraulics.
The bar (100,000 Pa) and the standard atmosphere (101,325 Pa) are exact; psi is derived from the pound-force and the inch, so its factor is a rounded value of an exact fraction.
