1.25 bar equals approximately 18.13 psi.
To convert bar to psi, multiply the pressure value in bar by 14.5038, since 1 bar equals 14.5038 psi. Therefore, multiplying 1.25 by 14.5038 gives the psi equivalent. This conversion is based on the precise relationship between these two pressure units, where bar is metric and psi is imperial.

Conversion Formula
The formula to convert bar to psi is: psi = bar × 14.5038. This works because 1 bar equals exactly 14.5038 pounds per square inch. By multiplying the value in bar by this factor, you directly get the pressure in psi. For example, for 2 bar: 2 × 14.5038 = 29.0076 psi.
Conversion Example
- Convert 0.5 bar:
- Multiply 0.5 by 14.5038
- Result: 0.5 × 14.5038 = 7.2519 psi
- Convert 2.5 bar:
- Multiply 2.5 by 14.5038
- Result: 2.5 × 14.5038 = 36.2595 psi
- Convert 10 bar:
- Multiply 10 by 14.5038
- Result: 10 × 14.5038 = 145.038 psi
- Convert 3.75 bar:
- Multiply 3.75 by 14.5038
- Result: 3.75 × 14.5038 = 54.3833 psi

Conversion Definitions
Bar
A bar is a metric unit of pressure, equal to 100,000 pascals, used to measure pressure in various applications like tires, hydraulics, and weather systems, providing a practical alternative to other pressure units.
Psi
Pounds per square inch (psi) is an imperial pressure measurement unit that indicates how many pounds of force are applied to one square inch of area, common in tire pressure, hydraulics, and industrial settings.
Conversion FAQs
How precise is the conversion from bar to psi?
The conversion factor of 14.5038 is exact, making the calculation highly precise for most engineering and measurement needs. Small rounding differences may occur depending on decimal places used but generally are negligible.
Can I convert negative pressure values from bar to psi?
Yes, negative pressure in bar can be converted to psi by multiplying the negative value by 14.5038, which is useful in contexts like vacuum measurements or pressure drops.
Why do some gauges use psi instead of bar?
Gauges in countries using imperial measurement systems display psi because it’s standard there, whereas metric countries prefer bar. The units reflect regional measurement preferences and industry standards.
Does temperature affect the pressure conversion between bar and psi?
Temperature impacts pressure readings generally but does not affect the conversion factor itself. The conversion remains constant regardless of temperature, assuming pressure is measured at the same conditions.
