Pressure converters
PSI, bar, kPa, atmospheres and mmHg for tires, compressors, weather and science.
Result
Precision (significant figures)
Formula
bar = psi × 0.0689476
1 psi = 0.0689476 bar
All pressure converters
| Converter | Units | Typical use |
|---|---|---|
| PSI to Bar | psi → bar | Tire pressure and compressors |
| Bar to PSI | bar → psi | European tire and espresso specs |
| kPa to PSI | kPa → psi | Metric tire placards |
| PSI to kPa | psi → kPa | Tire gauges and engineering specs |
Common situations
Why people usually need a pressure conversion, and which tool answers it.
The door sticker says 2.3 bar and the air pump reads psi (or kPa).
Three units for the same thing. The risk: under-inflated tires: worse grip, faster wear, more fuel.
