Enter the pressure in millimeters of mercury and the constant 760 into the calculator to determine the pressure in atmospheres. This calculator can also evaluate any of the variables given the others are known.

Mmhg To Atm Formula

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

ATM = MMHG / 760


  • ATM is the pressure in atmospheres
  • MMHG 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 Mmhg To Atm?

Mmhg to Atm is a conversion between two units of pressure. Mmhg, or millimeters of mercury, is a unit of pressure typically used in medicine and meteorology, while Atm, or atmosphere, is a unit of pressure often used in chemistry and physics. The conversion is used to express the same amount of pressure in different units, with 1 Atm being approximately equal to 760 Mmhg.

How to Calculate Mmhg To Atm?

The following steps outline how to convert pressure from mmHg to atm using the formula: ATM = MMHG / 760.

  1. First, determine the pressure in mmHg.
  2. Next, divide the pressure in mmHg by 760.
  3. Finally, calculate the pressure in atm.
  4. After inserting the pressure in mmHg and calculating the result, check your answer with the calculator above.
