The pressure on top of Mount Everest (29,029 ft or 8848 m) averages
about 235 mmHg. Convert this pressure to
\begin{equation}\begin{array}{ll}{\text { a. torr }} & {\text { b. psi }} \\ {\text { c. in Hg }} & {\text { d. atm }}\end{array}\end{equation}

Key Concepts

Dimensional Analysis

Dimensional analysis is a systematic approach used to convert units and verify the plausibility of equations by checking the consistency of the units. By systematically applying conversion factors, it ensures that calculations are coherent across different unit systems and that the final result retains the correct dimensional properties.

Pressure Units

There are several units used to measure pressure, such as mmHg, torr, psi, inches of mercury (in Hg), and atmospheres (atm). Although some of these units may appear different, many are related by fixed conversion factors. Familiarity with these units and their relationships allows for accurate conversion and comparison of pressure measurements in different settings.

Pressure

Pressure is the force exerted per unit area and is a fundamental concept in physics and engineering. It is measured in various units depending on the context, and understanding pressure is essential when analyzing phenomena in atmospheric science, fluid dynamics, and many other fields.

Unit Conversion

Unit conversion is the process of converting a measurement from one set of units to another using appropriate conversion factors. This concept involves using ratios based on equivalencies between units, ensuring that the units cancel appropriately so that the final value is expressed in the desired unit.
