Samantha NicoleThe conversion of 1.5 bar to psig results in approximately 21.75 psig. This is because 1 bar equals roughly 14.5 psig, so multiplying 1.5 by this factor gives the psig value.
To convert bar to psig, you multiply the pressure in bar by 14.5038, which is the approximate number of pounds per square inch gauge in one bar. This calculation accounts for the pressure difference between absolute and gauge pressure, where gauge pressure excludes atmospheric pressure.
Conversion Result
1.5 bar is equal to about 21.75 psig.

Conversion Formula
The formula to convert bar to psig is: psig = bar × 14.5038. This works because 1 bar equals exactly 14.5038 pounds per square inch gauge. To convert, you simply multiply the number of bar by this factor, which adjusts the pressure from absolute to gauge measurement.
For example, if you have 2 bar, the calculation is 2 × 14.5038 = 29.0076 psig. This step-by-step multiplication gives you the pressure in psig, reflecting how much above atmospheric pressure it is. The formula ensures accurate translation between units.
Conversion Example
- Convert 0.5 bar to psig:
- Multiply 0.5 by 14.5038
- 0.5 × 14.5038 = 7.2519 psig
- Convert 3 bar to psig:
- Multiply 3 by 14.5038
- 3 × 14.5038 = 43.5114 psig
- Convert 5.2 bar to psig:
- Multiply 5.2 by 14.5038
- 5.2 × 14.5038 = 75.5178 psig
- Convert 10 bar to psig:
- Multiply 10 by 14.5038
- 10 × 14.5038 = 145.038 psig

Conversion Definitions
bar
A measurement of pressure defined as 100,000 pascals or newtons per square meter, used internationally and in scientific contexts to quantify force exerted per unit area, especially in industrial and meteorological applications.
psig
Pounds per square inch gauge measures pressure relative to atmospheric pressure, indicating the pressure above atmospheric. It is commonly used in engineering and automotive fields, where readings are calibrated against atmospheric conditions.
Conversion FAQs
Why is the conversion factor for bar to psig 14.5038?
This factor comes from the exact definition that 1 bar equals 100,000 pascals, and since 1 psi equals 6894.76 pascals, dividing 100,000 by 6894.76 provides the conversion factor 14.5038, ensuring precise translation between the units.
Can I use the conversion formula for any pressure value?
Yes, the formula psig = bar × 14.5038 applies universally for converting bar to psig, regardless of the pressure magnitude, making it reliable for small or high-pressure measurements across various applications.
What is the difference between absolute pressure and gauge pressure?
Absolute pressure measures total pressure including atmospheric pressure, whereas gauge pressure excludes atmospheric pressure, indicating only the pressure above atmospheric level, which is what psig represents.
