Converting Pressure Units to Atmospheres

The video tutorial demonstrates how to convert 460 millimeters of mercury to atmospheres using a conversion factor. It begins by introducing the conversion factor of 1 atmosphere equals 760 mm of mercury. The tutorial then explains how to apply this factor to cancel out the units of mm of mercury, leaving atmospheres as the result. The calculation is performed step-by-step, resulting in a final value of 0.605 atmospheres. The video concludes by confirming the accuracy of the conversion.
