Russian standards are in bars (2.2 bar), American standards are in psi (32 psi). Translation: 1 bar ≈ 14.5 psi.
1 bar = 0.987 atm. For practical purposes, the 1.3% difference can be ignored.
Predicted pressure: mm Hg. Art. (Russia) or hectopascals (Europe). 760 mmHg Art. = 1013.25 hPa.
Always in mmHg. Art. Normal: 120/80. Hypertension: >140/90. Do not convert to other units for medical purposes.
| Application | Unit | Typical Range |
|---|---|---|
| Tires | bar/psi | 1.8–3.5 bar |
| Plumbing | bar | 2–6 bar |
| Gas cylinder | atm | 150–200 atm |
| Compressor | psi | 90–150 psi |
