How to convert Kilopascals to Atmospheres
To convert kilopascals to atmospheres, multiply by 0.00986923. One kilopascal equals 0.00986923 atm, and one atmosphere equals 101.325 kPa.
- Take the value in kilopascals — for example 7.5 kPa.
- Multiply by 0.00986923 (the number of atmospheres in one kilopascal).
- 7.5 × 0.00986923 = 0.0740192 atm.
Quick mental estimate: Divide the number of kilopascals by 101 (within 0.3% of the exact answer).

About converting Kilopascals to Atmospheres
Kilopascals (kPa) and Atmospheres (atm) are both units of pressure. The exact factor is 1 kPa = 0.00986923 atm, so multiply by 0.00986923 to go from kilopascals to atmospheres (or divide to go back).

Real-world pressure in kilopascals and atmospheres
| Example | Kilopascals | Atmospheres |
|---|---|---|
| A systolic blood pressure of 120 mmHg | 15.9987 kPa | 0.157895 atm |
| A pressure cooker's over-pressure (15 psi) | 103.4214 kPa | 1.020689 atm |
| The standard atmosphere | 101.325 kPa | 1 atm |
| A typical car tyre (32 psi) | 220.6322 kPa | 2.177471 atm |
| An espresso machine (9 bar) | 900 kPa | 8.882309 atm |
| A road-bike tyre (90 psi) | 620.5282 kPa | 6.124137 atm |
| A scuba cylinder (200 bar) | 20,000 kPa | 197.3847 atm |

The units
1,000 pascals.
Used for: Tyre pressure in Canada/Australia, weather and engineering.
The standard atmosphere: exactly 101,325 Pa, average sea-level air pressure.
Used for: Chemistry, diving and physics.
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.
