Psia and psig
WebPsig. Pounds per square in gauge, or psig, is a measure of pressure —but only a measurement of gauge pressure. This means that it is measured with respect to the atmospheric pressure. [1] The unit to measure psig is psi. In contrast to psig, psia is pounds per square inch absolute and it measures the absolute pressure, which is gauge pressure ... WebMay 29, 2024 · PSIG: This is the term used for PSI in relation to atmospheric pressure. PSIG is also known as Gauge Pressure. The ambient pressure at sea level is about 14.7 PSIA, but ambient PSIG is always 0. What PSI means? Pounds per square inch(PSI) is a common unit of pressure used in many different pressure measuring applications.
