Technical atmosphere quick reference
| Technical atmosphere | Bar | Pound-force per square inch | Pascal |
|---|---|---|---|
| 1 at | = 0.980665 bar | ≈ 14.22334331 psi | = 98066.5 Pa |
| 10 at | = 9.80665 bar | ≈ 142.2334331 psi | = 980665 Pa |
| 100 at | = 98.0665 bar | ≈ 1422.334331 psi | = 9806650 Pa |
| 1000 at | = 980.665 bar | ≈ 14223.34331 psi | = 98066500 Pa |
