Conversion Formula
The formula to convert bar to psi is: psi = bar × 14.5038. This works because 1 bar equals 14.5038 psi, a fixed conversion rate based on the relationship between metric and imperial pressure units. For example, if you have 2 bars, then psi = 2 × 14.5038 = 29.0076 psi.
Conversion Example
- Convert 5 bar to psi:
- Step 1: Take 5 as the input.
- Step 2: Multiply 5 by 14.5038.
- Step 3: 5 × 14.5038 = 72.519 psi.
- Convert 1.5 bar to psi:
- Step 1: Input 1.5.
- Step 2: Multiply 1.5 by 14.5038.
- Step 3: 1.5 × 14.5038 = 21.7557 psi.
- Convert 10 bar to psi:
- Step 1: Input 10.
- Step 2: Multiply 10 by 14.5038.
- Step 3: 10 × 14.5038 = 145.038 psi.

Conversion Definitions
Bar
A bar is a metric pressure unit equal to 100,000 Pascals, roughly the pressure exerted by Earth’s atmosphere at sea level, used in meteorology and engineering to measure pressure levels in liquids and gases.
Psi
Pounds per square inch (psi) is an imperial pressure unit expressing force in pounds applied over a square inch area, commonly used in the United States for tire pressures, hydraulic systems, and other pressure measurements.
Conversion FAQs
How accurate is the conversion from bar to psi?
The conversion uses a fixed factor of 14.5038, which provides high accuracy for most practical purposes. Variations are negligible for everyday pressure measurements, ensuring reliable conversion results across different applications.
Can I convert from psi back to bar using the same formula?
Yes, to convert psi to bar, divide the psi value by 14.5038. So, if you have 50 psi, dividing 50 by 14.5038 gives approximately 3.45 bar. This inverse calculation allows for bidirectional conversion between these units.
Why do different industries prefer one unit over the other?
Industries choose units based on regional standards or specific application needs. For example, automotive and tire industries in the U.S. prefer psi, while scientific and European contexts often use bar because of its metric basis and compatibility with SI units.
