Convert Atmospheres to torr
1 atmosphere = 760 torr · Torr = atm × 760
When you need this conversion
This conversion goes from atmospheres, pressure relative to sea level, used in diving and chemistry, to torr, equivalent to millimeters of mercury, used in vacuum work and medicine. Both measure the same physical quantity, so the conversion is exact — the difference is which unit your source, tool, or region happens to use.

The formula
Torr = atm × 760Because both units measure pressure, the conversion is a single multiplication by a fixed factor. That factor never changes, so the result is exact.
