What is Hg equal to?
In older literature, an "inch of mercury" is based on the height of a column of mercury at 60 °F (15.6 °C). In Imperial units: 1 inHg60 °F = 0.489 771 psi, or 2.041 771 inHg60 °F = 1 psi....

What is Hg in math?
Within the metric system, the abbreviation of hg refers to the hectogram. This is a unit of weight measurement, the basis for which is the gram.
What is Hg in pressure?
(or in Hg) Unit of atmospheric pressure used in the United States. The name comes from the use of mercurial barometers which equate the height of a column of mercury with air pressure. One inch of mercury is equivalent to 33.86 millibars or 25.40 millimeters. See barometric pressure.
What is a Hg weight?
A hectogram (hg) is a unit of mass/weight in the International System of Units (SI), the modern form of the metric system of measurement. 1 hectogram = 0.1 kilograms. 1 hectogram = 100 grams.
Is Hg and mmHg the same?
Two units of barometric pressure are millimeters of mercury (mm Hg) and inches of mercury (in Hg). As the pressure increases, the mercury rises higher in the barometer tube. ... Divide the pressure of mm Hg by 25.4 to convert to in Hg. In this example, divide 29 by 25.4 to get 1.14 in Hg.
How do you convert Hg to mmHg?
mmHg value = inHg value x 25.4 1 inch = 25.4 mm.
What is HG metric?
hecto- (symbol h) is a SI prefix in the SI system of units denoting a factor of 102 (100).
How do you convert DG to mg?
The conversion factor is 100; so 1 decigram = 100 miligrams. In other words, the value in dg multiply by 100 to get a value in mg.
How do you calculate mmHg?
The conversion calculation from inches of mercury column to millimetres of mercury column over the vacuum and atmospheric pressure range is as follows: 1 mmHg = 133.322 pascals (Pa) 1 inHg = 3386.39 pascals (Pa) mmHg value x 133.322 Pa = inHg value x 3386.39 Pa. mmHg value = inHg value x 25.4.
What is inches of Hg vacuum?
In the U.S., the common standard to measure rough vacuum is inches of mercury ("Hg), which can be measured in two different ways. One method is as "Hg gauge ("HgV), where the scale starts at 0" Hg (atmospheric pressure) and goes up to 29.92" Hg, which is perfect vacuum.
