Conversion Formula
The formula to convert psi to bar is: Pressure in bar = Pressure in psi × 0.0689476. This works because 1 psi equals approximately 0.0689476 bar, a ratio derived from the international standard for pressure units. Multiplying psi by this factor gives the pressure in bar.
For example, converting 50 psi: 50 × 0.0689476 = 3.44738 bar. Each psi value is scaled by this factor to translate it into bar, ensuring precise pressure readings across different measurement systems.
Conversion Example
- Convert 60 psi:
- Multiply 60 by 0.0689476
- 60 × 0.0689476 = 4.136856 bar
- Result: 60 psi equals approximately 4.137 bar
- Convert 25 psi:
- Multiply 25 by 0.0689476
- 25 × 0.0689476 = 1.72369 bar
- Result: 25 psi equals about 1.724 bar
- Convert 100 psi:
- Multiply 100 by 0.0689476
- 100 × 0.0689476 = 6.89476 bar
- Result: 100 psi is roughly 6.895 bar
- Convert 10 psi:
- Multiply 10 by 0.0689476
- 10 × 0.0689476 = 0.689476 bar
- Result: 10 psi equals approximately 0.689 bar
- Convert 80 psi:
- Multiply 80 by 0.0689476
- 80 × 0.0689476 = 5.515808 bar
- Result: 80 psi is about 5.516 bar

Conversion Definitions
psi
Psi, or pounds per square inch, measures pressure or force applied over a square inch. It is primarily used in the United States for tire pressure and other pressure measurements in various fields, indicating how much force is exerted per inch squared.
bar
Bar is a metric pressure unit equal to 100,000 pascals, or roughly the atmospheric pressure at sea level. It is used worldwide in scientific, industrial, and meteorological contexts to describe pressure levels, especially in Europe and other regions outside the US.
Conversion FAQs
Can I use the same conversion factor for all pressure ranges?
No, the conversion factor of 0.0689476 is accurate for standard pressure measurements. For extremely high or low pressures, specialized instruments or calibration might be necessary to ensure accuracy because measurement conditions could vary.
What if I want to convert bar back to psi?
To convert bar to psi, multiply the bar value by approximately 14.5038, because 1 bar equals about 14.5038 psi. This inverse conversion helps in cases where pressure readings are provided in bar but need to be understood in psi.
Is there a simple way to memorize this conversion?
A quick approximation is that 1 psi equals about 0.069 bar, so multiplying psi by 0.07 gives a close estimate. For precise work, always use the exact factor 0.0689476, but for rough calculations, 0.07 is sufficient.
Does temperature affect psi to bar conversions?
Temperature can influence pressure readings, especially in gases, because pressure and temperature are related through the ideal gas law. However, the conversion factor between psi and bar remains constant regardless of temperature, assuming ideal conditions.
Are there online calculators for psi to bar conversions?
Yes, numerous online tools and calculators allow quick conversions by inputting psi values and instantly getting the equivalent in bar. These tools use the standard conversion factor for accurate results without manual calculation errors.
