Per Google AI: Absolute vs. Gauge: Absolute units (like PSIA) measure up from a complete, theoretical zero-molecule vacuum. Relative or gauge vacuum measurements start at standard atmospheric pressure (~14.7 PSIA, 760 Torr, or 29.92 inHg), which translates to -14.7 PSIG, -29.92 inHg (rel), or -760 Torr on a gauge.
