Conversion Formula
The formula to convert bar to psi involves multiplying the pressure in bar by 14.5038, because 1 bar equals exactly 14.5038 psi. For example, to convert 1.25 bar: 1.25 × 14.5038 = 18.13 psi. This works because the conversion factor is a fixed ratio based on the definitions of the units.
Conversion Example
- Convert 2 bar to psi:
- Multiply 2 by 14.5038
- 2 × 14.5038 = 29.0076 psi
- Result is 29.01 psi (rounded to two decimal places)
- Convert 0.5 bar to psi:
- 0.5 × 14.5038 = 7.2519 psi
- Result is 7.25 psi
- Convert 5 bar to psi:
- 5 × 14.5038 = 72.519 psi
- Result is 72.52 psi
- Convert 10 bar to psi:
- 10 × 14.5038 = 145.038 psi
- Result is 145.04 psi

Conversion Definitions
Bar
A bar is a metric unit of pressure, equal to 100,000 pascals, used to measure force per unit area. It is common in meteorology and engineering to express atmospheric pressure or pressure within systems, providing a standard way to quantify force exerted over a surface.
Psi
Pounds per square inch (psi) is an imperial pressure measurement, representing the force in pounds applied over one square inch. It is used widely in the United States for tire pressures, hydraulics, and other pressure-related measurements in various industries.
Conversion FAQs
How accurate is the conversion from bar to psi?
The conversion uses a precise fixed ratio of 14.5038, making the calculation highly accurate for practical purposes. Minor variations may occur due to rounding, but for most applications, the result is reliable and consistent.
Can I convert psi back to bar using the same formula?
Yes, to reverse the conversion, divide the psi value by 14.5038. This allows you to switch from psi to bar directly, maintaining accuracy in both directions for pressure measurements.
What are typical pressure ranges in bar and psi?
Common pressure ranges vary depending on the application. For example, car tires often operate around 2-3 bar (29-44 psi), while industrial systems might reach higher levels. Knowing both units helps in understanding and maintaining equipment accurately.
Is 1 bar equivalent to atmospheric pressure?
Yes, 1 bar is roughly equal to standard atmospheric pressure at sea level, which is approximately 1.01325 bar or 14.7 psi. This makes bar a convenient unit for expressing atmospheric and weather-related pressure.
