About the Pressure converter
Pressure units vary by field: meteorologists use bar and pascals, tire gauges use PSI or bar, and scientists reference standard atmospheres. One standard atmosphere is exactly 101,325 pascals.
All units convert through the pascal, the SI unit equal to one newton per square meter. One bar is exactly 100,000 Pa and one PSI is about 6,894.76 Pa.
Common use cases
- Tire pressure between PSI and bar
- Weather reports in millibars (hPa)
- Scuba diving and depth pressure
- Engineering specifications across regions
Frequently asked questions
Most passenger cars recommend 30–35 PSI (about 2.1–2.4 bar). Check the sticker inside the driver's door for your vehicle's specification.
