Samantha NicoleThe conversion of 1.25 bar to psi is approximately 18.13 psi. This means that 1.25 bar equals about 18.13 pounds per square inch, a common pressure measurement used in various fields such as automotive and engineering.
To convert bar to psi, you multiply the value in bar by 14.5038 because 1 bar equals 14.5038 psi. This conversion factor comes from the definition of the pressure units, where bar is a metric unit based on atmospheric pressure, and psi is an imperial unit based on pounds per square inch. For example, 1.25 bar times 14.5038 gives approximately 18.13 psi.

Conversion Formula
The formula to convert bar to psi involves multiplying the number of bar by 14.5038 because this is the fixed conversion factor. The reason it works is that one bar equals exactly 14.5038 pounds per square inch, based on the physical definitions of these units. For example, for 1.25 bar, the math is:
- 1.25 bar * 14.5038 = 18.12975 psi
This calculation converts the metric measurement into the imperial measurement by applying this constant, ensuring accuracy for pressure conversions.
Conversion Example
- Convert 2 bar to psi:
- Multiply 2 by 14.5038
- 2 * 14.5038 = 29.0076 psi
- Convert 0.75 bar to psi:
- 0.75 * 14.5038 = 10.8779 psi
- Convert 5 bar to psi:
- 5 * 14.5038 = 72.519 psi
- Convert 10 bar to psi:
- 10 * 14.5038 = 145.038 psi
- Convert 4.5 bar to psi:
- 4.5 * 14.5038 = 65.266 psi

Conversion Definitions
Bar
Bar is a metric pressure unit, defined as 100,000 pascals, roughly equivalent to atmospheric pressure at sea level. It’s used worldwide for measuring pressure in various applications like weather, industry, and engineering.
Psi
Pounds per square inch (psi) is an imperial pressure measurement that indicates how many pounds of force are applied to one square inch of area. It’s common in the United States for measuring tire pressure, hydraulics, and other pressure-related systems.
Conversion FAQs
How precise is the conversion from 1.25 bar to psi?
The conversion uses a fixed factor of 14.5038, making it very accurate. Small variations might occur due to rounding, but generally, the result is precise enough for most practical purposes, including engineering and automotive needs.
Can I use the same conversion factor for all pressure conversions?
Yes, the factor 14.5038 is constant because it’s based on the definitions of the units. However, if conversions involve other units, different factors are needed, but for bar to psi, this number remains standard.
Why is psi used instead of bar in some countries?
Because psi is an imperial unit, it’s primarily used in the United States and some industries there. Countries using the metric system prefer bar or pascals, but psi remains popular for specific applications like tire pressure.
Can I convert psi back to bar with the same method?
Yes, to convert psi to bar, divide the psi value by 14.5038. For example, 18 psi divided by 14.5038 gives approximately 1.24 bar.
What other pressure units can I convert to from bar?
From bar, you can convert to pascals, atmospheres, psi, and kilopascals, each requiring its specific conversion factor. These are used depending on the industry or measurement standard involved.
