Samantha NicoleThe conversion of 12 barg is approximately 174 psi.
Since 1 bar gauge (barg) equals 14.5038 pounds per square inch (psi), multiplying 12 barg by this factor gives the psi value. This means 12 barg translates directly to 12 times 14.5038 psi, resulting in around 174.0456 psi.

Conversion Formula
The conversion from barg to psi follows the formula: psi = barg × 14.5038. This works because 1 bar gauge equals 14.5038 psi. To convert any barg value to psi, multiply the barg by this factor. For example, for 12 barg: 12 × 14.5038 = 174.0456 psi.
Conversion Example
- Example 1: Convert 5 barg to psi.
- Multiply 5 by 14.5038.
- 5 × 14.5038 = 72.519 psi.
- Example 2: Convert 20 barg to psi.
- Multiply 20 by 14.5038.
- 20 × 14.5038 = 290.076 psi.
- Example 3: Convert 0.5 barg to psi.
- Multiply 0.5 by 14.5038.
- 0.5 × 14.5038 = 7.2519 psi.
- Example 4: Convert 15 barg to psi.
- Multiply 15 by 14.5038.
- 15 × 14.5038 = 217.557 psi.

Conversion Definitions
barg
Barg (bar gauge) measures pressure relative to atmospheric pressure, indicating how much above atmospheric pressure a system is. It does not include atmospheric pressure in its reading, focusing only on the pressure exerted by the contained fluid.
psi
Pounds per square inch (psi) is a unit of pressure measuring force in pounds applied over an area of one square inch. It is commonly used in the US for tire pressures, hydraulic systems, and other industrial pressure measurements.
Conversion FAQs
What is the main difference between bar and psi?
Bar is a metric unit measuring pressure, with 1 bar approximately equal to 14.5038 psi. Psi is an imperial unit. The main difference lies in their measurement systems: metric versus imperial, with psi being more common in the US.
Why is the conversion factor 14.5038 used?
This factor is derived from the exact equivalence between 1 bar and 14.5038 pounds per square inch, based on precise definitions of pressure units. It ensures accurate conversion from metric to imperial pressure units.
Can I use this conversion for absolute pressure?
Not directly. The conversion applies to gauge pressure (barg), which measures pressure above atmospheric pressure. Absolute pressure adds atmospheric pressure (about 14.7 psi at sea level) to the gauge value, so convert accordingly.
How accurate is the conversion from barg to psi?
The conversion uses a fixed factor of 14.5038, which is very precise for most practical purposes. However, slight variations may occur due to temperature changes or measurement tolerances, but for typical uses, it is sufficiently accurate.
