To convert 320 mmHg to atmospheres, you can use the conversion factor: 1 atmosphere (atm) is equal to 760 mmHg.
The conversion formula is: Pressure in atmospheres (atm) = Pressure in millimeters of mercury (mmHg) / 760
For your specific example: Pressure in atmospheres = 320 mmHg / 760
Calculating this: Pressure in atmospheres is approximately 0.421 atm
So, 320 mmHg is approximately equal to 0.421 atmospheres.
Essentially, you multiply the mmHg given by the conversion factor 1 atm/760 mmHg. The units mmHg cancel out, leaving atm, which is what we are trying to find.
Note that atmospheric pressure varies with altitude, and the conversion factor may not be accurate at locations significantly above or below sea level.
