How much is 10 psig equal to in psia?

To convert from gauge pressure (psig) to absolute pressure (psia), you need to add the atmospheric pressure to the gauge pressure. Atmospheric pressure at sea level is typically about 14.7 psi.

In this case, 10 psig indicates that the pressure is 10 psi above the atmospheric pressure. Therefore, you would calculate the absolute pressure as follows:

10 psig + 14.7 psi (atmospheric pressure) = 24.7 psia.

This calculation clearly shows that 10 psig is equivalent to 24.7 psia, making it the appropriate choice. Understanding this conversion is crucial in fields such as plant operations, where accurately measuring and interpreting pressures is essential for equipment operation and safety.
