What is gauge pressure


Pressure is represented by defining atmospheric pressure as zero. Pressure higher than atmospheric pressure is positive pressure, while pressure lower than atmospheric pressure is negative pressure.

Note: Atmospheric pressure varies depending on the weather, the altitude, etc. Therefore, a gauge pressure measuring instrument in which atmospheric pressure is defined as zero may not display the pressure value under absolute vacuum as “-760 mmHg”.
