# How do you convert inches to atmospheric pressure?

## How do you convert inches to atmospheric pressure?

To convert 28 inches of mercury to atmospheres, divide 28 by the 29.92. This yields a result of 0.936 atmosphere. To convert back to inches, multiply 0.936 by 29.92. The conversion requires adjustment at temperatures higher or lower than zero degrees Celsius.

## How many inches is 30 mmHg?

Millimeters of mercury to Inches of Mercury table

Millimeters of mercury Inches of Mercury
27 mmHg 1.06
28 mmHg 1.10
29 mmHg 1.14
30 mmHg 1.18

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. For example, if you have 29 mm Hg, multiply 29 by 0.03937 to get 1.14 in Hg. Divide the pressure of mm Hg by 25.4 to convert to in Hg.

### How do you calculate mmHg?

As discussed earlier we know that one millimetre of mercury is the pressure exerted by a 1mm vertical column of mercury at 0 degree Celsius. And we also know that one mmHg is also equal to 1 torr, which is 1 / 760 of atmospheric pressure (atm) that is 1 atm = 760 mmHg.

### 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.

Is barometric pressure measured in inches?

Although the standard pressure at sea level is measured in PSI, barometric pressure is typically measured in either inches of mercury (inHg or “Hg) or millibars.

What is mmHg full form?

mmHg. abbreviation for. millimetre(s) of mercury (a unit of pressure equal to the pressure that can support a column of mercury 1 millimetre high)

### Why is mmHg used?

MmHg means millimetres of mercury (Hg = mercury) and is used in EU member states and Switzerland to measure the pressure of body fluids, such as eg blood pressure. The unit mmHg (millimeter mercury column) is also used to measure blood pressure.

### What does mmHg mean?

millimeters of mercury
The abbreviation “mm Hg” means millimeters of mercury, the height of a column of mercury, as in a blood pressure reading. Mercury is poisonous to people.

What does 30 inch mercury mean?

It is the total weight of all the air above that object. An air pressure of 30 inches means the mercury will have risen to a height of exactly 30 inches.
