The formula to convert mmHg to atm is:
\[ \text{ATM} = \frac{\text{MM}}{760} \]
Where:
mmHg 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 required to support a column of mercury 760 millimeters high at 0 degrees Celsius at sea level. Therefore, to convert from mmHg to atm, you divide the pressure in mmHg by 760.
Let's consider an example:
Using the formula to convert mmHg to atm:
\[ \text{ATM} = \frac{1520}{760} = 2.000000 \, \text{atm} \]
This means that a pressure of 1520 mmHg is equivalent to 2.000000 atm.
