When you do the dimensional analysis it makes sure that the math is working out right It makes sure that you re getting the right units But even with this let s try a slightly more complicated example Let s say that our rate is let s say let s keep our rate at 5 meters per second but let s say that someone gave us the time Example 1.4 Using Dimensions to Remember an Equation Suppose we need the formula for the area of a circle for some computation. Like many people who learned geometry too long ago to recall with any certainty, two expressions may pop into our mind when we think of circles: π r 2 and 2 π r.

Dimensional Analysis Example ProblemsThese calculations are examples of a versatile mathematical approach known as dimensional analysis (or the factor-label method ). Dimensional analysis is based on this premise: the units of quantities must be subjected to the same mathematical operations as their associated numbers. Example 1 Sally walked 2 45 miles How far did she walk in yards Example 2 Sally walked 3 95 kilometers How far did she walk in meters These values correspond to the same distance However there are 1000 meters in a kilometer but 1760 yards in a mile
