The conversion of 1.5 bar results in approximately 21.75 psig.
Since 1 bar equals about 14.5038 psig, multiplying 1.5 by this factor gives the pressure in psig. This direct conversion helps in understanding pressure differences measured in bar when expressed in pounds per square inch gauge, which is more common in the US measurement system.
Result for 1.5 bar to psig
1.5 bar equals approximately 21.75 psig, achieved by multiplying 1.5 by 14.5038, the conversion factor from bar to psig. This conversion provides a quick way to understand pressure readings in different measurement systems, especially in industrial and scientific contexts where psig is standard.

Conversion Formula
The conversion from bar to psig relies on the fact that 1 bar equals approximately 14.5038 psig. This comes from the relationship between absolute pressure and gauge pressure, where gauge pressure excludes atmospheric pressure. The formula multiplies the bar value by 14.5038 to get psig.
For example, if you have 2 bars, multiply 2 by 14.5038: 2 × 14.5038 = 29.0076 psig. This calculation works because the conversion factor is a fixed constant derived from the pressure units’ definitions, making it straightforward to convert between these two units.
Conversion Example
- Convert 3 bars to psig:
- Step 1: Take the value in bar, which is 3.
- Step 2: Multiply 3 by 14.5038 (conversion factor).
- Step 3: 3 × 14.5038 = 43.5114 psig.
- Result: 3 bars equals approximately 43.5114 psig.
- Convert 0.75 bars to psig:
- Step 1: Value in bar is 0.75.
- Step 2: Multiply 0.75 by 14.5038.
- Step 3: 0.75 × 14.5038 = 10.8779 psig.
- Result: 0.75 bars equals approximately 10.8779 psig.
- Convert 5 bars to psig:
- Step 1: Value in bar is 5.
- Step 2: Multiply 5 by 14.5038.
- Step 3: 5 × 14.5038 = 72.519 psig.
- Result: 5 bars equals approximately 72.519 psig.

Conversion Definitions
Bar
The bar is a metric unit of pressure equal to 100,000 pascals, used mainly in weather, engineering, and industrial measurements. It provides a convenient way to express pressure levels, especially in contexts where SI units are preferred, but is not an SI unit itself.
Psig
Psig stands for pounds per square inch gauge, measuring pressure relative to atmospheric pressure. It indicates the pressure above atmospheric pressure, used widely in the US for tire, tank, and industrial pressure readings, providing a familiar scale for many users.
Conversion FAQs
Why is the conversion factor 14.5038 from bar to psig?
This factor stems from the relationship between absolute pressure units. Since 1 bar equals 100,000 pascals and 1 psi equals 6894.76 pascals, dividing 100,000 by 6894.76 results in approximately 14.5038. This number converts bar directly to psig, which is gauge pressure.
Can I use a calculator to convert pressure from bar to psig?
Yes, using a calculator simplifies the process. Just multiply the bar value by 14.5038 to get psig. For example, if you input 2 in the calculator, it will display 29.0076 psig automatically, saving time and ensuring accuracy.
What is the difference between bar and psig?
The main difference is that bar is an absolute pressure unit, while psig measures gauge pressure, which excludes atmospheric pressure. Gauge pressure indicates the pressure above atmospheric pressure, making it more relevant for many practical applications.
How do temperature changes affect these pressure conversions?
Temperature can influence pressure readings because gases expand or contract with temperature. However, the conversion factor between bar and psig remains constant regardless of temperature, since it is based on fixed pressure units, not gas behavior.
Is there a standard pressure measurement in bar or psig for industrial tanks?
Many industries use psig for everyday measurements, but bar can be used for international or scientific standards. The choice depends on regional practices; in the US, psig is common, while in Europe, bar might be more prevalent for tank pressures.
