Conversion Formula
The formula to convert bar to psi is: psi = bar × 14.5038. This works because the measurement of pressure in bar is scaled to psi through this fixed conversion factor. For example, if you have 1 bar, multiplying it by 14.5038 gives approximately 14.5038 psi. To convert 3.1 bar, multiply 3.1 by 14.5038, resulting in about 44.95 psi.
Conversion Example
- Convert 2 bar to psi:
- Multiply 2 by 14.5038
- 2 × 14.5038 = 29.0076 psi
- Convert 5.5 bar to psi:
- 5.5 × 14.5038 = 79.7709 psi
- Convert 0.5 bar to psi:
- 0.5 × 14.5038 = 7.2519 psi
- Convert 10 bar to psi:
- 10 × 14.5038 = 145.038 psi
- Convert 1.75 bar to psi:
- 1.75 × 14.5038 = 25.3806 psi

Conversion Definitions
Bar
The bar is a metric unit of pressure equal to 100,000 Pascals, roughly the atmospheric pressure at sea level. It’s commonly used in engineering and meteorology to measure force per unit area, especially in contexts like tire pressure and industrial applications.
Psi
Pounds per square inch (psi) measures pressure as force in pounds applied over one square inch. It’s widely used in the United States for tire pressures, hydraulic systems, and other applications where pressure measurement is needed in imperial units.
Conversion FAQs
How accurate is the conversion from bar to psi?
The conversion uses a fixed ratio of 14.5038, so calculations are precise within the limits of decimal rounding. For most practical purposes, this provides sufficiently accurate results, especially in engineering and everyday applications.
Can I use this conversion for gases at different temperatures?
This conversion assumes standard conditions and typical pressure units. For gases at varying temperatures or in non-standard conditions, pressure readings may differ, and more complex calculations involving temperature and volume might be necessary.
Is there a difference in converting pressure units for liquids versus gases?
No, the conversion between bar and psi is purely a measurement of force over area; it applies equally to liquids and gases. However, the actual pressure might vary depending on the physical state and context, but the unit conversion remains the same.
What tools can I use besides this webpage to convert bar to psi?
Besides manual calculations, you can use scientific calculators, conversion apps, or software like Excel with formulas to accurately convert bar to psi for various measurements.
Why do different industries prefer either bar or psi?
Industries choose units based on regional standards and application types. Europe often uses bar for engineering and meteorology, while the United States prefers psi for automotive and hydraulic industries, influencing measurement preferences globally.
