Conversions Between Pressure Units

The video tutorial explains how to convert 330 millimeters of mercury to atmospheres using a conversion factor. It begins by introducing the conversion factor, which states that one atmosphere equals 760 mm of mercury. The tutorial then demonstrates how to apply this factor by multiplying 330 mm of mercury by the conversion factor, ensuring that the units of mm of mercury cancel out, leaving the result in atmospheres. The final calculation yields a result of approximately 0.434 atmospheres, confirming the correct setup and execution of the conversion process.

What is the conversion factor used to convert millimeters of mercury to atmospheres?

• 1 atmosphere equals 1000 mm of mercury

• 1 atmosphere equals 1013 mm of mercury
