Conversion Factors and Dimensional Analysis

Conversion Factors

• A conversion factor is a ratio that represents equality between two values.
• It enables the transformation from one unit measurement to another without altering the value.

Dimensional Analysis

• Dimensional analysis utilizes conversion factors to switch between units effectively.
• It is essential that the initial unit is placed in the denominator of the conversion factor to facilitate the proper cancellation of units.

Purpose of Dimensional Analysis

• The main goal of dimensional analysis is to obtain a new unit of measure that differs from the original measurement.
• It is a systematic approach to ensure that the units being calculated are correct and consistent.

Process of Dimensional Analysis

• The fundamental approach to dimensional analysis can be expressed mathematically as:
  • Given unit A x ([unit B]/[unit A]) x ([unit C]/[unit B]) = [unit C]
• This formula illustrates the step-by-step method to convert units through the use of ratios.
