1. Blood pressure is normally measured in gauge pressure , which is the pressure above atmospheric. 2. "I'm not sure how to gauge pressure , " he said. 3. Torr and micron usually indicates an absolute pressure, while inHg usually indicates a gauge pressure . 4. For most working fluids where a fluid exists in a closed system, gauge pressure measurement prevails. 5. As the internal temperature rises, the pressure also rises until it reaches the design gauge pressure . 6. "Bar ( a ) " and " bara " are sometimes used to indicate gauge pressures . 7. Testing involves exposure to higher gauge pressures than design levels, or in some cases, pulling harder vacuum. 8. Gauge pressure ( also spelled " gage " pressure ) is the pressure relative to the ambient pressure.9. Absolute cold tire pressure ( gauge pressure plus atmospheric pressure ) varies directly with the absolute temperature, measured in kelvins. 10. Bourdon tubes measure gauge pressure , relative to ambient atmospheric pressure, as opposed to absolute pressure; vacuum is sensed as a reverse motion.
