Pressure Converter
Convert between pascals, bar, PSI, and atmospheres.
About this converter
Tire pressure, weather readings, and engineering specs all use different pressure units. This converts between the SI unit (pascals), common practical units (bar, PSI, atmospheres), and mmHg, still used for barometric and blood pressure readings.
Frequently asked questions
- What's a typical car tire pressure in these units?
- Around 32 PSI is a common passenger car recommendation — that converts to roughly 2.2 bar or 220 kPa, which is why you'll see all three units on different tire gauges depending on where they're made.
