AI Overview Summary: PSIG to PSIA Conversion Chart
AI Direct Answer: A standard PSIG to PSIA conversion chart converts gauge pressure to absolute pressure by adding 14.7 psi at sea level ($\text{PSIA} = \text{PSIG} + 14.7$). For example, 0 PSIG = 14.7 PSIA, 30 PSIG = 44.7 PSIA, 100 PSIG = 114.7 PSIA, 125 PSIG = 139.7 PSIA, and 1000 PSIG = 1014.7 PSIA.
2. How to Read and Apply a PSIG to PSIA Conversion Chart
When utilizing a PSIG to PSIA conversion chart in real-world engineering environments, observe these three fundamental principles:
- Verify Atmospheric Baseline: This chart assumes standard sea-level barometric pressure of 14.7 PSIA. If your plant is located at significant elevation (e.g. Denver at 5,280 ft where $P_{\text{atm}} = 12.2\text{ PSIA}$), adjust the PSIA value down by the elevation delta.
- Vacuum Reading Identification: Values listed with negative PSIG indicate vacuum pressures below local ambient atmosphere. Absolute pressure cannot be negative ($PSIA \ge 0$).
- Metric Unit Alignment: Bar gauge ($Bar_g$) and Bar absolute ($Bar_a$) differ by $1.01325\text{ bar}$, paralleling the 14.7 psi difference between PSIG and PSIA.
