PSI to Bar: Complete Pressure Conversion Guide
Converting PSI to bar is essential when working with equipment that uses metric specifications or international standards. Our PSI to bar converter provides accurate conversions using the precise conversion factor of 1 PSI = 0.0689476 bar.
PSI to Bar Conversion Formula
Bar = PSI × 0.0689476
This conversion factor is derived from the exact relationship: 1 PSI = 6,894.757 Pa and 1 bar = 100,000 Pa, giving us 0.06894757 bar per PSI.
How to Convert PSI to Bar
- Take the pressure value in PSI
- Multiply by 0.06895 to get bar
- Round to appropriate decimal places
- Verify using our conversion table
Common PSI to Bar Conversions
- 14.504 PSI = 1 bar (atmospheric pressure)
- 30 PSI = 2.068 bar (typical car tire pressure)
- 50 PSI = 3.447 bar (bicycle tire pressure)
- 100 PSI = 6.895 bar (industrial applications)
When to Use PSI to Bar Conversion
PSI to bar conversion is needed when working with international equipment specifications, European automotive standards, hydraulic system documentation, compressed air systems in metric countries, and scientific equipment calibration.
Understanding PSI and Bar Units
PSI (pounds per square inch) is widely used in the United States for tire pressure, hydraulic systems, and industrial equipment. Bar is a metric unit preferred in Europe and scientific applications, making conversions between these units essential for international work.
Conversion Accuracy
Our converter uses the precise factor of 0.06894757 bar per PSI, ensuring accuracy for engineering calculations, equipment specifications, and scientific measurements. The simplified factor 0.06895 is sufficient for most practical applications.
