Conversion Formula
The formula to convert bar to psi multiplies the pressure value in bar by 14.5038, because 1 bar equals 14.5038 psi. This conversion works because it directly relates the two units through their defined equivalence, ensuring accurate pressure measurement conversions.
For example, if you have 2 bar, multiply 2 by 14.5038: 2 × 14.5038 = 29.0076 psi. This calculation transforms the pressure from the metric to the imperial system, making it easier to interpret in different contexts.
Conversion Example
- Convert 5 bar to psi:
- Step 1: Take 5 (pressure in bar).
- Step 2: Multiply 5 by 14.5038.
- Step 3: 5 × 14.5038 = 72.519 psi.
- Convert 10 bar to psi:
- Step 1: Use 10 as the pressure value.
- Step 2: Multiply 10 by 14.5038.
- Step 3: 10 × 14.5038 = 145.038 psi.
- Convert 1.5 bar to psi:
- Step 1: Use 1.5.
- Step 2: Multiply 1.5 by 14.5038.
- Step 3: 1.5 × 14.5038 = 21.7557 psi.

Conversion Definitions
Bar
A bar is a metric unit of pressure equal to 100,000 pascals, roughly the atmospheric pressure at sea level, used mainly in meteorology and engineering to measure force per unit area.
Psi
Pounds per square inch (psi) measures pressure as force in pounds applied over one square inch, common in the US for tire pressures, hydraulics, and industrial pressure systems.
