What is the relationship between Standard atmosphere and Torr?

One Standard atmosphere (atm) is defined as exactly 101,325 pascals and equals approximately 760 Torr, where one Torr is 1/760 of an atmosphere.

In which fields is converting atm to Torr commonly used?

This conversion is often used in chemical thermodynamics, vacuum systems, semiconductor fabrication, diving, and analytical instrumentation.

Can I use Torr for general atmospheric pressure measurements?

Torr is generally best for low pressure and vacuum contexts, while atm is suitable for general atmospheric pressure measurements.
