Dimensional Analysis Introduction Dimensional analysis is also known as unit conversion, factor analysis, factor label, factor unit system, unit analysis, DA, and unit multipliers. You have a great advantage once you understand dimensional analysis. You only need to know one definition about any new unit you are introduced to in order to use it to convert that unit in any problem. Dimensional analysis is a tool used in obtaining most science math solutions. Dimensional analysis is a technique that is used to change any unit(s) from one to another. There are three basic concepts that are used in unit conversion: 1. We can multiply or divide any quantity by one , and the result will still be equal to the original quantity. Ex. 6 ( 1 ) = 6 2. The numeral one (1) can be written in many different ways when written in a fraction form. Ex. 1 2 3 4 10 11 . 1 2 3 4 10 11 feet miles etc feet miles = = = = = = = = = 1 As long as the numerator of the fraction equals the denominator of the fraction,(1 =-1, 2 = 2, 3 = 3, etc.), the fraction is equal to one (1). Any definition involving units can
