PSI to Bar Converter

Use our PSI to Bar converter to quickly and accurately convert pressure from pounds per square inch (psi) to bar. Enter a pressure value in the calculator below to instantly find the equivalent pressure in bar.

How to Convert PSI to Bar

To convert PSI to bar, multiply the pressure in psi by 0.0689475729. One pound per square inch equals approximately 0.0689475729 bar.

Formula

bar = psi × 0.0689475729

Example: Convert 35 psi to bar.
35 × 0.0689475729 = 2.4131650515
35 psi ≈ 2.413165 bar

PSI to Bar Conversion Chart

Common Tire Pressure Conversions

PSI to bar conversions are commonly useful when reading tire-pressure information on vehicles, gauges, inflators, and equipment that use different pressure units. For quick reference, 30 psi ≈ 2.07 bar, 32 psi ≈ 2.21 bar, 35 psi ≈ 2.41 bar, 36 psi ≈ 2.48 bar, and 40 psi ≈ 2.76 bar.

These values are conversion examples only. Always use the tire pressure recommended by the vehicle or tire manufacturer rather than selecting a pressure based on the examples above.

For exact pressure values, use the PSI to Bar converter above instead of relying on rounded conversion examples.

About PSI

PSI stands for pounds per square inch and is a unit of pressure commonly used in the United States. It describes the amount of force in pounds applied over an area of one square inch.

About Bar

The bar is a metric unit of pressure commonly used in automotive, industrial, meteorological, and engineering contexts. One bar equals 100,000 pascals (Pa).

For additional information about metric measurement and SI units, visit the U.S. National Institute of Standards and Technology (NIST).

Understanding the difference between these pressure measurement systems is especially useful when comparing vehicles, equipment, gauges, or specifications from different countries. PSI is commonly used for pressure measurements in the United States, while bar is widely used in automotive and industrial applications around the world. Whether you are checking tire pressure, using an air compressor, reading a pressure gauge, or comparing equipment specifications, an accurate PSI to bar conversion helps ensure that you are working with the correct pressure value.

For fast and accurate results, use our PSI to Bar converter whenever you need to compare pressure measurements between pounds per square inch (psi) and bar.
