Converting Millimeters of Mercury

The video tutorial explains how to convert 740 mm of mercury to atmospheres (ATM). It begins by introducing the concept of conversion and the need for a conversion factor. The tutorial then explains that one atmosphere is equal to 760 mm of mercury, which can be memorized or looked up. The process involves multiplying 740 mm of mercury by the conversion factor, ensuring that mm of mercury cancels out, leaving the result in ATM. The calculation involves dividing 740 by 760, resulting in approximately 0.974 ATM. The tutorial concludes with a summary of the conversion process.

What is the conversion factor from millimeters of mercury to atmospheres?

• 1 atm = 750 mm of mercury

• 1 atm = 740 mm of mercury

• 1 atm = 720 mm of mercury

• 1 atm = 760 mm of mercury

Why is it important to place millimeters of mercury on the bottom of the conversion factor?

• To increase the final value

• To ensure the units cancel out correctly

• To make the calculation easier

• To decrease the final value
