Pressure Converter: Convert Between Pa, bar, psi, atm, torr and More

Introduction

Pressure measurements are critical in engineering, meteorology, medicine, and automotive maintenance. Our pressure converter handles all standard pressure units with precision.

Conversion Formulas and Factors

The pascal is the SI base unit for pressure:

1 bar = 100,000 Pa = 100 kPa 1 PSI = 6894.75729 Pa 1 atm = 101,325 Pa = 1.01325 bar 1 torr = 133.322368 Pa 1 mmHg = 133.322387 Pa

Key relationships:

1 atm = 14.6959 PSI 1 bar = 14.5038 PSI 1 atm = 760 torr = 760 mmHg

How to Use the Converter

Our pressure converter supports all common units. For example, to convert 32 PSI to bar: 32 PSI = 2.206 bar � typical car tire pressure.

Real-World Examples

Automotive: Recommended tire pressure of 35 PSI is 2.41 bar. Weather: Standard atmospheric pressure is 1013.25 hPa = 29.92 inHg. Scuba Diving: At 30 meters depth, the pressure is approximately 4 atm.

Common Applications

• Automotive: Tire pressure monitoring and air suspension systems
• Weather Forecasting: Barometric pressure measurements
• Medicine: Blood pressure measured in mmHg
• Engineering: Hydraulic systems, boilers, and pressure vessels
• Scuba Diving: Calculating air supply duration

Tips for Accurate Conversions

1. 1. Distinguish between absolute pressure and gauge pressure
2. 2. 1 bar is very close to 1 atm (only 1.3% difference)
3. 3. In weather, hectopascals (hPa) are equivalent to millibars (mbar)

Conclusion

Pressure conversions are essential in automotive care, weather, medicine, and engineering. Our pressure converter provides instant, accurate conversions. For more tools, see the complete guide to unit converters.
