It also gives the correct answer for absolute pressure. assuming you are measuring psia. which is the pressure relative to absolute zero vacuum. These are the vacuum pressure ranges as measured in torr (or fractions of 1. This is where vacuum lifting equipment and numerous other industrial applications operate.

The symbol hg stands for its latinized greek name hydrargyrum. meaning watery or liquid silver. In the u.s.. the common standard to measure rough vacuum is inches of mercury (hg). which can be measured in two different ways.

#### Torr (Mm Hg) In Hg (Inches Mercury) Kpa (Si Unit) Bar.

What does hg mean in vacuum? Mercury is a metal on the periodic table of elements with a symbol of hg. It also gives the correct answer for absolute pressure. assuming you are measuring psia. which is the pressure relative to absolute zero vacuum.

#### 0% Vacuum = 760 Torr = 14.7 Psia = 29.92 Inc Mercury Abs = 101.4 Kpa Abs.

It measures how much the pressure is lower than atmospheric pressure. Psi (relative to atmosphere) in hg (relative to vacuum) Even smaller is the micron. defined as 0.001 torr.

#### Hg. In Terms Of Vacuum. Is An Abbreviation For Either Millimeters Or Inches Of Mercury. Depending On The Type Of Measurement.

The vacuum range that can be measured in units of mercury (hg) is called the rough vacuum range. Vacuum gauges are used to diagnose engine problems by measuring manifold pressure. In the u.s.. the common standard to measure rough vacuum is inches of mercury (“hg). which can be measured in two different ways.

#### Keeping This In Consideration. Why Is Hg Vacuum.

These are the vacuum pressure ranges as measured in torr (or fractions of 1. If you are measuring relative to vacuum and want to resolve the pressure relative to the atmosphere. then you should use the form below. Vacuum is defined as air pressure below atmospheric pressure the vacuum level is the difference in pressure between atmospheric pressure and pressure in the evacuated system:

#### This Gage Displays Two Different Units Of Pressure:

Any fraction of an atmosphere is a partial vacuum and equates with negative gauge pressure. One method is as “hg gauge (“hgv). where the scale starts at 0″ hg (atmospheric pressure) and. In air conditioning and refrigeration. inhg is often used to describe inches of mercury vacuum. or pressures below ambient atmospheric pressure. for recovery of refrigerants from air conditioning and refrigeration systems. as well as for leak testing of systems while under a vacuum. and for dehydration of refrigeration systems.
