To convert torr to atm (atmospheres), you can use a simple conversion factor. The relationship between torr and atm is based on the definition of standard atmospheric pressure.
1 atm is equal to 760 torr. Therefore, to convert torr to atm, you divide the number of torr by 760.
**Formula:**
\[ \text{atm} = \frac{\text{torr}}{760} \]
**Example:**
If you have 1520 torr and want to convert it to atm, you would do the following calculation:
\[ \text{atm} = \frac{1520}{760} = 2 \]
So, 1520 torr is equal to 2 atm.
This conversion is straightforward and is commonly used in various scientific and engineering applications, especially when dealing with pressure measurements.
