<P> In engineering and science , dimensional analysis is the analysis of the relationships between different physical quantities by identifying their base quantities ( such as length , mass , time , and electric charge ) and units of measure ( such as miles vs. kilometers , or pounds vs. kilograms vs. grams ) and tracking these dimensions as calculations or comparisons are performed . Converting from one dimensional unit to another is often somewhat complex . Dimensional analysis , or more specifically the factor - label method , also known as the unit - factor method , is a widely used technique for such conversions using the rules of algebra . </P>
