Pressure Conversion and Relationships

The video tutorial explains how to convert between millimeters of mercury (mmHg) and kilopascals (kPa), two units of pressure. It begins by introducing the relationship between these units, where 760 mmHg equals 101.325 kPa. The tutorial then demonstrates the conversion process from mmHg to kPa using a conversion factor, followed by a reverse conversion from kPa to mmHg. Each conversion is a one-step process involving multiplication and division. The video concludes with a summary and encourages viewers to explore additional resources.

What is the relationship between millimeters of mercury and kilopascals?

• 101.325 mmHg = 760 kPa

• 760 mmHg = 101.325 kPa

• 1 mmHg = 1 kPa

• 760 mmHg = 1 kPa

To convert 851 mmHg to kPa, which conversion factor should be used?

• 101.325 kPa / 760 mmHg

• 1 kPa / 1 mmHg

• 760 mmHg / 101.325 kPa

• 851 mmHg / 101.325 kPa

What is the first step in converting 851 mmHg to kPa?

• Multiply by 760

• Divide by 101.325

• Multiply by 101.325

• Divide by 760

After calculating, what is the rounded value of 851 mmHg in kPa to three significant figures?

• 101 kPa
