Key Concepts

Pressure Units

Pressure is a measure of force applied per unit area. Common units for pressure include pascals (Pa), atmospheres (atm), and millimeters of mercury (mmHg). Understanding these units is essential for converting between them, as they represent the same physical quantity but in different scales.

Conversion Factors

Conversion factors are ratios that express how many of one unit are equal to another unit. For pressure, the conversion factor between pascals and atmospheres is 1 atm = 101,325 Pa. Using this factor allows for the straightforward conversion of pressure measurements from one unit to another.

Dimensional Analysis

Dimensional analysis is a mathematical technique used to convert units by multiplying by appropriate conversion factors. This method ensures that units cancel appropriately, leading to the desired unit in the final answer. It is a critical skill in chemistry for ensuring accuracy in calculations involving different measurement systems.
