Conversion Formula
The conversion from bar to psi is based on multiplying the pressure in bar by 14.5038. This formula works because 1 bar equals exactly 14.5038 psi. For example, if you have 2 bar, multiply 2 by 14.5038 to get 29.0076 psi. Each pressure unit in bar can be directly converted by this multiplication.
Mathematically, the formula is: Pressure in psi = Pressure in bar × 14.5038. This works because the two units are different measures of pressure, and 14.5038 is the fixed conversion constant between them.
Conversion Example
- Convert 3 bar to psi:
- Step 1: Write down the value in bar: 3
- Step 2: Multiply by 14.5038: 3 × 14.5038
- Step 3: Calculate: 43.5114 psi
- Result: 3 bar equals approximately 43.5114 psi.
- Convert 0.5 bar to psi:
- Step 1: Write down 0.5 in bar.
- Step 2: Multiply by 14.5038: 0.5 × 14.5038
- Step 3: Result is 7.2519 psi.
- Answer: 0.5 bar is about 7.2519 psi.
- Convert 5 bar to psi:
- Step 1: Start with 5 in bar.
- Step 2: Multiply 5 by 14.5038: 72.519
- Result: 5 bar equals roughly 72.519 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 for measuring pressure in various fields, including meteorology, engineering, and fluid systems, providing a standard for pressure comparison.
Psi
Psi, pounds per square inch, is a pressure measurement in the imperial system, representing the force in pounds applied over a square inch area. It is widely used in the United States for tire pressures, hydraulic systems, and other pressure related measurements.
Conversion FAQs
How precise is the conversion factor 14.5038 for bar to psi?
The factor 14.5038 is an exact value used internationally, based on the definition of the pascal and pound-force per square inch. It provides high accuracy, suitable for most engineering and scientific calculations without the need for further adjustment.
Can I convert pressure from bar to psi without a calculator?
Yes, by multiplying the pressure in bar by 14.5038, you can convert without a calculator if you know basic multiplication. For quick estimates, approximate the factor as 14.5, but for precise work, use the full value.
Does temperature affect the conversion from bar to psi?
Temperature does not directly change the conversion factor but can influence the pressure readings themselves. The conversion formula assumes constant temperature conditions; significant temperature variations may cause pressure changes unrelated to unit conversion.
