    Dimensional analysis is the use of units in an equation/derivation to check the validity of the process. In practical terms, many use the term to mean using a conversion factor. For example, suppose we wish to convert 100 cm to 1 m and we know the factor is 1 m = 100 cm. Therefore,
    100 cm x (1 m/100 cm) = 1 meter. Note how the cm unit in the numerator cancels with the cm unit in the denominator leaving the unit we want to keep all alone.
