Conversion Formula
The formula to convert bar to psi involves multiplying the number of bar by 14.5038, the conversion factor. This works because 1 bar equals exactly 14.5038 psi. For example, to convert 2 bar: 2 x 14.5038 = 29.0076 psi. Each unit of bar is scaled by this factor to find psi.
This calculation applies directly because pressure units are based on fixed relationships, allowing simple multiplication to switch between them without complex adjustments.
Conversion Example
- Convert 0.5 bar:
- Multiply 0.5 by 14.5038
- 0.5 x 14.5038 = 7.2519 psi
- Convert 3 bar:
- 3 x 14.5038 = 43.5114 psi
- Convert 10 bar:
- 10 x 14.5038 = 145.038 psi
- Convert 5.75 bar:
- 5.75 x 14.5038 = 83.385 psi
- Convert 1.2 bar:
- 1.2 x 14.5038 = 17.4046 psi

Conversion Definitions
Bar
Bar is a metric unit measuring pressure, defined as 100,000 pascals, roughly equal to atmospheric pressure at sea level. It is used in various industries for pressure measurement, especially in meteorology and engineering.
Psi
Pounds per square inch (psi) measures pressure by how many pounds of force are applied over one square inch. It is widely used in the US for tire pressure, hydraulics, and other pressure related applications, based on imperial units.
Conversion FAQs
How accurate is converting 1.55 bar to psi?
The conversion using 14.5038 as the factor is precise, so the result of approximately 22.49 psi for 1.55 bar is highly accurate for practical purposes. Minor variations can occur due to rounding but are insignificant in most contexts.
Can I use a different conversion factor for bar to psi?
While 14.5038 is the standard exact conversion factor, some approximate factors like 14.5 are used for quick mental calculations. However, for precise results, sticking to 14.5038 provides the most accurate conversion.
Why does pressure measurement differ between bar and psi?
These units originate from different measurement systems—metric and imperial—so their numerical values differ. The conversion factor links them, allowing pressure expressed in one system to be accurately translated into the other.
What is the significance of converting bar to psi?
Converting between these units helps in understanding pressure measurements across different regions and industries, ensuring compatibility of equipment, safety standards, and technical specifications worldwide.
