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.
