Understanding the Units of Pressure

Pressure is a fundamental physical quantity that is measured in various units, including millimeters of mercury (mmHg) and kilopascals (kPa). In this article, we will explore the conversion between these two units, with a focus on converting 2,150 mmHg to kPa.

The Relationship Between mmHg and kPa

The relationship between mmHg and kPa is based on the definition of the pascal (Pa), which is the SI unit of pressure. One pascal is equal to one newton per square meter (N/m²). To convert mmHg to kPa, we need to use the following conversion factor:

1 mmHg = 0.133322 kPa

Converting 2,150 mmHg to kPa

Now that we have the conversion factor, we can convert 2,150 mmHg to kPa by multiplying the value in mmHg by the conversion factor:

2,150 mmHg × 0.133322 kPa/mmHg = 286.5 kPa

Rounding the Answer

The answer we obtained is 286.5 kPa. However, we need to consider the options provided in the question. The closest option is 287 kPa, which is the correct answer.

Conclusion

In this article, we have explored the conversion between mmHg and kPa, with a focus on converting 2,150 mmHg to kPa. We have used the conversion factor to obtain the correct answer, which is 287 kPa. This conversion is essential in various fields, including medicine, engineering, and science, where pressure is a critical parameter.
