Gauge pressure to atmospheric pressure

WebThis lower atmospheric pressure expresses itself as a lower gauge pressure, which looks like the zero is off. Quick recap: Gauge pressure = absolute pressure – atmospheric pressure. Using the pressurization examples above: 30 psig = 44.7 psia – 14.7 psi (atmospheric pressure at sea level) 0 psig = 14.7 psia – 14.7 psi (again, at sea level) WebMar 29, 2024 · The primary difference between absolute and gauge pressure lies in their reference points. Absolute pressure is measured against a complete vacuum or absolute zero pressure, whereas gauge pressure is measured relative to the local atmospheric pressure. As a result, absolute pressure represents the total pressure exerted by a …
