For a designer suit, Daniel must specify his waist size in centimeters. If there are 12  inches in a foot and 30.5 centimeters in a foot, then what size should Daniel specify, in centimeters, if his waist size in inches is 34 inches?

Using dimensional analysis, we have

 

34 in  x  [ 1 ft] / [12 in]  x [ 30.5 cm] / [1 ft ]      cancel units and we are left with

 

34 x  [30.5 /12] cm  =

 

34 * 30.5  /12   cm   ≈  86.42 cm
