Conversion Formula
The conversion formula from bar to psi multiplies the number of bar units by 14.5038, because 1 bar equals 14.5038 psi. So, to convert, take the pressure in bar and multiply it. For example, 3.8 bar times 14.5038 equals approximately 55.1 psi. This works because the units are based on different measurement systems but are directly proportional.
Conversion Example
- Convert 2 bar to psi:
- 2 x 14.5038 = 29.0076 psi
- Convert 5.5 bar to psi:
- 5.5 x 14.5038 = 79.770 psi
- Convert 10 bar to psi:
- 10 x 14.5038 = 145.038 psi
- Convert 0.75 bar to psi:
- 0.75 x 14.5038 = 10.877 psi
- Convert 7.2 bar to psi:
- 7.2 x 14.5038 = 104.4266 psi

Conversion Definitions
Bar
A bar is a metric unit of pressure equal to 100,000 pascals, roughly the atmospheric pressure at sea level. It is used worldwide in many fields to measure force per unit area, 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 of area. It is common in the United States for tire pressures, hydraulics, and other pressure measurement needs.
