Conversion Formula
The conversion from bar to psi involves multiplying the pressure in bar by 14.5038 because this figure is the precise equivalence between the two units. The formula is: psi = bar x 14.5038, which allows a direct calculation of the pressure in pounds per square inch.
This works because the units are based on different measurement systems: bar in the metric system and psi in the imperial system. The constant 14.5038 bridges these scales, ensuring accurate conversions for pressure readings.
For example, to convert 2 bar to psi: 2 x 14.5038 = 29.0076 psi, demonstrating how the formula is applied step-by-step for each value.
Conversion Example
- Convert 5 bar to psi:
- Step 1: Write the formula: psi = 5 x 14.5038
- Step 2: Multiply 5 by 14.5038: 5 x 14.5038 = 72.519 psi
- Result: 5 bar equals 72.519 psi
- Convert 1.5 bar to psi:
- Step 1: Use the formula: psi = 1.5 x 14.5038
- Step 2: Multiply 1.5 by 14.5038: 1.5 x 14.5038 = 21.7557 psi
- Result: 1.5 bar equals 21.7557 psi
- Convert 10 bar to psi:
- Step 1: Write the formula: psi = 10 x 14.5038
- Step 2: Multiply 10 by 14.5038: 10 x 14.5038 = 145.038 psi
- Result: 10 bar equals 145.038 psi

Conversion Definitions
A bar is a metric unit of pressure, nearly equal to the atmospheric pressure at sea level, and used in various scientific and industrial contexts. It is a convenient unit for measuring gases and liquids, based on the force exerted over an area.
Psi, or pounds per square inch, is an imperial unit measuring pressure, representing the force in pounds applied over one square inch of area. It is commonly used in the United States for automotive, aviation, and industrial applications.
Conversion FAQs
How accurate is the conversion from bar to psi?
The conversion factor of 14.5038 is exact, so calculations based on it are highly precise. However, measurement errors can occur due to instrument calibration or environmental factors, but the conversion itself maintains high accuracy.
Can I use this conversion for gas pressure in tanks?
Yes, pressure readings in tanks often use bar or psi, and the conversion applies equally. Just ensure the measurement units are correctly identified before converting to avoid misinterpretation of the pressure level.
Why is psi more common in the US whereas bar is used elsewhere?
The imperial system, including psi, is historically prevalent in the US, while metric units like bar are standard in most other countries. Different industries and standards influence the choice, but conversions allow interchangeability.
What tools can I use to convert pressure units quickly?
Online converters, calculator apps, and embedded conversion tools on websites or devices provide instant and accurate conversions between bar and psi, saving time compared to manual calculations.
