Conversion Definitions

The following is a list of definitions relating to conversions between mmHg and atmospheres.

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.

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.

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 mmHg to atm is:

atm = mmHg ÷ 760

Conversion Example

Next, let's look at an example showing the work and calculations that are involved in converting from millimeters of mercury to atmospheres (mmHg to atm).

mmHg to Atmosphere Conversion Example

Task: Convert 975 mmHg to atmospheres (show work) Formula: mmHg ÷ 760 = atm Calculations: 975 mmHg ÷ 760 = 1.28289474 atm Result: 975 mmHg is equal to 1.28289474 atm
