Conversion Definitions
The following is a list of definitions relating to conversions between atmospheres and mmHg.
What is an atmosphere (atm)?
An atmosphere (or standard atmosphere) is a non-SI unit of Pressure. The symbol for atmosphere is atm. There are 0.00131579 atmospheres in a mmHg.
What is millimeters of mercury (mmHg)?
Millimeters of mercury is a non-SI unit of Pressure. The symbol for millimeters of mercury is mmHg. There are 760 mmHg in an atmosphere.
Conversion Formula
Let's take a closer look at the conversion formula so that you can do these conversions yourself with a calculator or with an old-fashioned pencil and paper.
The formula to convert from atm to mmHg is:
mmHg = atm x 760
Conversion Example
Next, let's look at an example showing the work and calculations that are involved in converting from atmospheres to millimeters of mercury (atm to mmHg).
Atmosphere to mmHg Conversion Example
Task: Convert 8 atmospheres to mmHg (show work) Formula: atm x 760 = mmHg Calculations: 8 atm x 760 = 6,080 mmHg Result: 8 atm is equal to 6,080 mmHg
