Conversion Formula
The formula to convert bar to psi is: psi = bar × 14.5038. This works because 1 bar equals exactly 14.5038 psi. Therefore, multiplying the number of bars by this factor provides the psi pressure. For example, converting 3.4 bar involves calculating 3.4 × 14.5038, resulting in 49.2909 psi.
Conversion Example
- Convert 2 bar to psi:
- Step 1: Write the formula: psi = 2 × 14.5038
- Step 2: Multiply 2 by 14.5038: 2 × 14.5038 = 29.0076
- Step 3: Result: 29.0076 psi
- Convert 1.5 bar to psi:
- Step 1: Write the formula: psi = 1.5 × 14.5038
- Step 2: Multiply 1.5 by 14.5038: 1.5 × 14.5038 = 21.7557
- Step 3: Result: 21.7557 psi
- Convert 5 bar to psi:
- Step 1: Write the formula: psi = 5 × 14.5038
- Step 2: Multiply 5 by 14.5038: 5 × 14.5038 = 72.519
- Step 3: Result: 72.519 psi

Conversion Definitions
Bar
A bar is a metric unit of pressure equal to 100,000 pascals, used to measure force exerted over an area, commonly in meteorology and engineering to express atmospheric or system pressures.
Psi
Pounds per square inch (psi) is a pressure unit measuring force in pounds applied over one square inch of area, widely used in the United States for tire pressure, hydraulics, and other pressure-related measurements.
Conversion FAQs
How accurate is converting 3.4 bar to psi using the factor 14.5038?
The conversion factor 14.5038 is precise and commonly accepted, making the result very accurate for practical purposes. Minor variations may occur due to rounding, but for most applications, this conversion is sufficiently reliable.
Can I convert other pressure units to psi using the same method?
No, different units require different conversion factors. For example, converting from atmospheres or pascals involves different multipliers or formulas. Always use the correct factor for the specific unit you are converting from.
