Conversion Formula
The formula to convert bar to psi multiplies the bar value by 14.5038 because 1 bar equals 14.5038 psi. This works due to the definition of pressure units, where psi measures pounds per square inch and bar measures force per area. For example, 1 bar x 14.5038 = 14.5038 psi.
For 0.4 bar, the math is 0.4 x 14.5038, resulting in 5.80152 psi. This multiplication scales the pressure from metric to imperial units, providing an accurate conversion between these two common measurement systems.
Conversion Example
- Convert 1.2 bar to psi:
- Step 1: Use the formula: 1.2 x 14.5038.
- Step 2: Calculate 1.2 x 14.5038 = 17.40456 psi.
- Result: 1.2 bar equals approximately 17.4046 psi.
- Convert 2.5 bar to psi:
- Step 1: Multiply 2.5 by 14.5038.
- Step 2: 2.5 x 14.5038 = 36.2595 psi.
- Result: 2.5 bar equals around 36.2595 psi.
- Convert 0.1 bar to psi:
- Step 1: Multiply 0.1 by 14.5038.
- Step 2: 0.1 x 14.5038 = 1.45038 psi.
- Result: 0.1 bar equals about 1.4504 psi.

Conversion Definitions
Bar
The bar is a metric unit of pressure measuring force per unit area, where 1 bar equals 100,000 pascals or newtons per square meter, used mainly in meteorology, engineering, and industrial contexts to quantify pressure levels.
Psi
Pounds per square inch (psi) is an imperial measurement of pressure, representing force in pounds applied over one square inch, widely used in automotive, tire, and hydraulic systems to specify pressure levels.
