A vacuum gauge is used to measure the pressure in a vacuum, usually relative to the atmospheric pressure of the immediate surroundings….Pressure Vacuum Conversion.

Manometers use a column of liquid, usually either water or mercury (Hg) to measure relative pressure. How do you convert air pressure into a vacuum? To calculate the pump capacity required to bring the vacuum to a higher level, we convert the vacuum levels quoted to absolute terms: How do you calculate the flow rate of a vacuum pump? To show the relationship between “Hg gauge and “Hg absolute, we can use the following example: 26″ Hg gauge at sea level would be 29.92 – 26 = 3.92” Hg absolute. Please note that a perfect vacuum is not possible on earth, no matter which vacuum pump is used. How do you convert Hg vacuum to Hg absolute?
