How is dimensional analysis used for unit conversion? - Answers

Dimensional analysis is a mathematical technique used to convert units by analyzing the dimensions of physical quantities. It involves setting up conversion factors that express the relationship between different units, allowing for the cancellation of units in calculations. By multiplying the quantity in the original unit by the appropriate conversion factors, one can systematically convert it to the desired unit while ensuring that the dimensions remain consistent throughout the process. This method is particularly useful for ensuring accuracy and clarity in scientific calculations.
