The conversion of 1.5 bar equals approximately 21.75 psig.
Since 1 bar equals 14.5038 psi (pounds per square inch gauge), multiplying 1.5 by this factor gives the pressure in psig, which is commonly used in various engineering and industrial applications to measure pressure above atmospheric pressure.
Pressure Conversion: From Bar to psig
To convert bar to psig, you multiply the pressure value in bar by 14.5038, which is the number of pounds per square inch gauge in one bar. This works because each bar is defined as exactly 100,000 pascals, and 1 psi is approximately 6894.76 pascals. The conversion factor simplifies this relationship.

Conversion Formula
The formula to convert bar to psig is: psig = bar * 14.5038. This formula works because 1 bar equals 14.5038 psi, which is the pressure measurement above atmospheric pressure in pounds per square inch. The conversion ensures that you get the pressure in psig directly from bar.
For example, if you have 2 bar, then: 2 * 14.5038 = 29.0076 psig, meaning that 2 bar of pressure is equivalent to 29.0076 pounds per square inch gauge.
Conversion Example
- Convert 0.5 bar:
- Multiply 0.5 by 14.5038
- 0.5 * 14.5038 = 7.2519 psig
- So, 0.5 bar equals 7.2519 psig.
- Convert 3 bar:
- 3 * 14.5038 = 43.5114 psig
- This shows that 3 bar equals 43.5114 psig.
- Convert 5.2 bar:
- 5.2 * 14.5038 = 75.5188 psig
- Thus, 5.2 bar is roughly 75.5188 psig.

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 to measure pressure in various scientific and industrial contexts, especially where metric units are preferred for standardization.
psig
Psig stands for pounds per square inch gauge, a unit measuring pressure relative to atmospheric pressure. It indicates the pressure in pounds per square inch above the atmospheric pressure, commonly used in engineering and manufacturing to specify system pressures.
Conversion FAQs
How accurate is the conversion from 1.5 bar to psig?
The conversion uses a fixed factor of 14.5038, making it highly accurate for practical purposes. Minor variations might occur due to rounding, but for most engineering and industrial needs, this conversion is sufficiently precise.
Can I use the same formula for converting other pressure units?
No, this formula specifically converts bar to psig. Different units like pascals, atmospheres, or torr require their own conversion factors. Always verify the appropriate factor when dealing with other pressure units.
Why is psig preferred over psia in some cases?
Psig measures pressure relative to atmospheric pressure, which is useful in applications like tires or tanks, where the pressure above atmospheric is relevant. Psia includes atmospheric pressure in its measurement, which can be less practical for certain systems.
What happens if I input a negative value in the converter?
Negative values in pressure may represent vacuum conditions or negative gauge pressure, indicating pressure below atmospheric. The converter will reflect this as a negative psig, which is meaningful in specific contexts like vacuum systems.
