Enter the pressure in millimeters of mercury and the constant 760 into the calculator to determine the pressure in atmospheres.

Mm To Atm Formula

The following formula is used to calculate the conversion from millimeters of mercury (mmHg) to atmospheres (atm).

ATM = MM / 760

Variables:

  • ATM is the pressure in atmospheres
  • MM is the pressure in millimeters of mercury

To calculate the pressure in atmospheres, divide the pressure in millimeters of mercury by 760.

What is a Mm To Atm?

Mm to Atm refers to the conversion from millimeters of mercury (mmHg) to atmospheres (atm), which are both units of pressure. One atmosphere is defined as the pressure necessary to support a column of mercury 760 millimeters high at 0 degrees Celsius at sea level. Therefore, to convert from mmHg to atm, you would divide the pressure in mmHg by 760.

How to Calculate Mm To Atm?

The following steps outline how to calculate the pressure in atmospheres (ATM) from millimeters of mercury (MM) using the formula: ATM = MM / 760.


  1. First, determine the pressure in millimeters of mercury (MM).
  2. Next, divide the pressure in millimeters of mercury (MM) by 760.
  3. Finally, calculate the pressure in atmospheres (ATM).
  4. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

Pressure in millimeters of mercury (MM) = 570
