How to convert PSIG to PSIA? PSIG to PSIA conversion

Now, let's look at how the PSIG to PSIA calculator works. The conversion from pounds per square inch gauge (PSIG) to pounds per square inch absolute (PSIA) is a fundamental process in various fields of engineering and science, where accuracy in pressure measurements is essential. For professionals and students involved in fluid dynamics, thermodynamics, and a range of other technical applications, a thorough understanding of this conversion is crucial for ensuring precision and consistency in their measurements.

  • The conversion from PSIG to PSIA involves a simple formula:

    PSIA=PSIG+14.7\text{PSIA} = \text{PSIG} + 14.7

    This formula accounts for the fact that PSIG measures pressure relative to atmospheric pressure, which is approximately 14.7 PSI at sea level. By adding this atmospheric pressure value to the gauge pressure, we obtain the absolute pressure.

  • Example of using the PSIG to PSIA converter:

    To illustrate, let's convert 30 PSIG to PSIA:

    PSIA=30+14.744.7 PSIA\text{PSIA} = 30 + 14.7 ≈ 44.7 \text{ PSIA}

    Therefore, 30 PSIG is equivalent to approximately 44.7 PSIA.

This conversion process is more than just a numerical task; it's integral in ensuring accurate and consistent pressure measurements across different systems. Such accuracy is vital for effective communication and collaboration in various engineering disciplines and across international boundaries. It also supports uniformity in research, manufacturing, and quality control.

Moreover, accurate conversion from PSIG to PSIA is especially critical in industries like aerospace, automotive, and maritime engineering, where precise pressure measurement is vital for system design, safety, and regulatory compliance. The standardized conversion helps engineers and scientists to compare and interpret pressure data effectively, making it an indispensable tool in the engineering and scientific community.


How do I convert PSIG to PSIA?

You can convert PSIG into PSIA in three steps:

  1. Identify the PSIG value to convert.
  2. Remember the conversion factor, which is 14.7. (This is because atmospheric pressure at sea level is approximately 14.7 PSI, and PSIA includes atmospheric pressure)
  3. Apply the PSIA conversion formula: PSIA = PSIG + 14.7.

What is the PSIA if the pressure is 150 PSIG?

The pressure in PSIA for 150 PSIG would be approximately 164.7 PSIA. You can calculate this using the formula: PSIA = PSIG + 14.7, where 14.7 PSI is the average atmospheric pressure at sea level.

Does the conversion from PSIG to PSIA depend on temperature?

No, the conversion between PSIG and PSIA is based purely on pressure and is not affected by temperature.

Are PSIG and PSIA units used worldwide?

PSIG and PSIA are predominantly used in countries that use the Imperial system. Other countries might use different units like Pascals or bars.
