These calculations are examples of a versatile mathematical approach known as dimensional analysis -LRB- or the factor-label method -RRB- . Dimensional analysis is based on this premise : the units of quantities must be subjected to the same mathematical operations as their associated numbers . This method can be applied to computations ranging from simple unit conversions to more complex , multi-step calculations involving several different quantities . A ratio of two equivalent quantities expressed with different measurement units can be used as a unit conversion factor . For example , the lengths of 2.54 cm and 1 in .
