The conversion of 12 barg results in approximately 174 psi.
Since 1 barg equals 14.5038 psi, multiplying 12 by this factor gives about 174 psi, meaning that 12 barg is equivalent to that pressure in pounds per square inch, a common measurement in pressure systems.
Pressure Conversion from barg to psi
The conversion from barg to psi is based on the fact that 1 bar gauge (barg) is equal to 14.5038 pounds per square inch. To convert a value in barg to psi, you multiply the barg value by 14.5038. This works because both units measure pressure, with psi being an imperial unit and barg a metric one, adjusted for gauge pressure.

Conversion Formula
The formula to convert barg to psi is straightforward: multiply the number of barg by 14.5038. This is because 1 barg equals 14.5038 psi; thus, scaling the value directly provides the pressure in psi. For example, converting 5 barg: 5 x 14.5038 = 72.519 psi. This formula ensures accurate translation between the units, making it easy to switch from metric to imperial pressure measurements.
Conversion Example
- Convert 20 barg to psi:
- Multiply 20 by 14.5038
- 20 x 14.5038 = 290.076 psi
- This means 20 barg is equal to 290.076 psi
- Convert 7.5 barg to psi:
- 7.5 x 14.5038 = 108.878 psi
- So, 7.5 barg equals approximately 108.878 psi
- Convert 3.2 barg to psi:
- 3.2 x 14.5038 = 46.411 psi
- Thus, 3.2 barg is about 46.411 psi
- Convert 15.6 barg to psi:
- 15.6 x 14.5038 = 226.219 psi
- Meaning 15.6 barg pressure is roughly 226.219 psi

Conversion Definitions
barg
Barg stands for bar gauge, a pressure unit measuring the pressure relative to atmospheric pressure. It equals atmospheric pressure plus the absolute pressure, used mainly in industrial contexts to specify pressure above atmospheric level.
psi
Pounds per square inch (psi) is an imperial unit measuring pressure, representing the force in pounds applied over one square inch area. Commonly used in the US for tire pressure, hydraulics, and other pressure measurements.
Conversion FAQs
What does 12 barg mean in terms of absolute pressure?
12 barg indicates pressure above atmospheric pressure, so the absolute pressure is about 12 plus 1 atm (14.5038 psi), totaling roughly 188.5 psi absolute. To find the absolute value, add atmospheric pressure to gauge pressure.
Why is the conversion factor 14.5038 used for barg to psi?
This factor is based on the fact that 1 bar equals 14.5038 psi. Since barg measures gauge pressure, the same ratio applies for converting to imperial units, providing an accurate measure of pressure in pounds per square inch.
Can I convert psi back to barg easily?
Yes. To convert psi to barg, divide the psi value by 14.5038. For example, 174 psi divided by 14.5038 gives approximately 12 barg, making the reverse conversion straightforward.
Is 12 barg pressure safe for industrial equipment?
Pressure safety depends on the equipment specifications. 12 barg equals about 174 psi, which is within the operational limits for many industrial systems, but always verify equipment ratings before applying such pressures.
What is the typical pressure in psi for 12 barg in water systems?
In water systems, 12 barg translates to approximately 174 psi, a pressure often used in high-pressure water jetting or industrial cleaning applications, indicating substantial force involved.
