Conversion Formula
The formula to convert psi to bar involves multiplying the psi value by 0.0689476, because 1 psi equals 0.0689476 bar. This works because the units are defined by pressure standards, where bar is a metric unit of pressure. For example, to convert 43 psi:
- Multiply 43 by 0.0689476
- 43 × 0.0689476 = 2.97126
- Result: approximately 2.97 bar
Conversion Example
Suppose you want to convert 55 psi to bar. Here’s how:
- Step 1: Take the psi value, which is 55
- Step 2: Multiply by 0.0689476
- Step 3: 55 × 0.0689476 = 3.7911
- Step 4: The value in bar is about 3.79
Another example, converting 20 psi:
- Step 1: Value is 20 psi
- Step 2: Multiply 20 by 0.0689476
- Step 3: 20 × 0.0689476 = 1.378952
- Step 4: Result rounds to 1.38 bar

Conversion Definitions
Psi (pounds per square inch) measures pressure based on force (pounds) applied over an area (square inch), mainly used in the US for tire pressure. Bar is a metric pressure unit, representing atmospheric pressure at sea level, used internationally in scientific and industrial contexts.
Conversion FAQs
Why is the conversion factor between psi and bar 0.0689476?
This factor comes from the international standard where 1 psi equals 0.0689476 bar, derived from the relationship between pounds-force and Newtons, and inches to meters. It ensures precise pressure conversions across different measurement systems.
Can I convert psi to other metric units like pascals using the same method?
Not exactly. While psi to bar multiplies by 0.0689476, to convert psi to pascals, you multiply by 6894.76, because 1 psi equals 6894.76 pascals. Each conversion has its specific factor based on the units involved.
Is the conversion accurate for very high pressures?
Yes, the conversion using the factor 0.0689476 remains accurate for high pressures, as it is based on the defined relationship between psi and bar. However, measurement precision depends on the accuracy of the original pressure gauge.
