How to Convert Mercury to atm?

To convert mercury (mmHg) to atmospheres (atm), you need to divide the mercury pressure value by the standard atmospheric pressure in mmHg.

Conversion Process

Here's how to convert from millimeters of mercury (mmHg) to atmospheres (atm):

1. Know the Conversion Factor: 1 atm is equal to 760 mmHg.

2. Divide: Divide the pressure in mmHg by 760 to get the equivalent pressure in atm.

Formula:

Pressure in atm = Pressure in mmHg / 760

Example

Let's say you have a pressure of 700 mmHg and want to convert it to atm:

Pressure in atm = 700 mmHg / 760

Pressure in atm ≈ 0.921 atm

Therefore, 700 mmHg is approximately equal to 0.921 atm.

Summary

To convert mmHg to atm, simply divide the mmHg value by 760. This calculation provides the equivalent pressure in atmospheres.
