Conversions Between Pressure Units

The video tutorial explains how to convert 360 mm of mercury to atmospheres using a conversion factor. It begins by introducing the conversion factor, which is 1 atmosphere equals 760 mm of mercury. The tutorial then demonstrates how to set up the conversion by placing 760 mm of mercury in the denominator and 1 atmosphere in the numerator. The calculation is performed, and the units of mm of mercury cancel out, leaving the result in atmospheres. The final result is approximately 0.474 atmospheres. Dr. B concludes the tutorial by confirming the correct setup and thanking viewers for watching.
