How to Convert mmHg to atm

Converting mmHg to atm is a relatively simple process. Understanding the basics of atmospheric pressure and the units used to measure it is essential to understanding the conversion process. This article will explain the formula and steps needed to convert millimeters of mercury (mmHg) to atmospheres (atm).

## What is Atmospheric Pressure?

Contents

Atmospheric pressure is the pressure exerted by the atmosphere of Earth (or any other planet) on the surface of the planet. It is measured in various units, such as millimeters of mercury (mmHg), atmospheres (atm), and torr. Atmospheric pressure decreases with altitude, and is typically around 101.3 kPa or 760 mmHg at sea level.

## What is mmHg?

Millimeters of mercury (mmHg) is a unit of pressure that is commonly used in meteorology and barometry. It is defined as the pressure exerted by a column of mercury 1 millimeter high at the Earth’s surface. It is derived from the unit of pressure, torr, which is named after Italian physicist Evangelista Torricelli, who determined the first barometer.

## What is atm?

Atmosphere (atm) is a unit of pressure that is commonly used in meteorology. It is defined as the pressure that is exerted by the Earth’s atmosphere at sea level. This unit of pressure is equal to 101.325 kPa or 760 mmHg.

## How to Convert mmHg to atm

To convert mmHg to atm, use the following formula:

atm = mmHg Ã· 760

For example, if you have a pressure reading of 1060 mmHg, the corresponding atm value would be 1060 Ã· 760 = 1.38 atm.

## How to Convert atm to mmHg

Conversely, to convert atm to mmHg, use the formula:

mmHg = atm Ã— 760

For example, if you have a pressure reading of 1.38 atm, the corresponding mmHg value would be 1.38 Ã— 760 = 1060 mmHg.

## Conclusion

Converting mmHg to atm and vice-versa is a relatively simple process. All you need to do is remember the simple formula and apply the appropriate conversion factor. With this information, you can quickly and accurately convert between the two units of pressure.
