To use dimensional analysis to facilitate the conversion of units. Dimensional analysis is amongst the most valuable tools physical scientists use. Simply put, it is the conversion between an amount in one unit to the corresponding amount in a desired unit using various conversion factors. In the previous post, we talked about conversion factors and their use in dimensional analysis. Remember, in short, the conversion factors are the ratios of the units for the given quantity. For example, we know that 1 ft is 12 in, and therefore, we can derive two conversion factors by simply getting the ratio of these units: Solution: Select a conversion factor which will convert the unit "cm" to the unit "mm". The appropriate conversion factor is: 10 mm / 1 cm.
