Nursing Preparation Study Guide Example Convert 2 yards into inches. Step 1: Start with your given amount and divide it by one. 2 yards 1 Step 2: Identify a conversion factor that will relate your factor to the next. This might require more than one conversion factor. • 1 yard = 3 feet • 1 foot = 12 inches Step 3: Multiply your original amount by the conversion factors. Set these factors up as a fraction so that the original unit is on the bottom and the new unit is on the top. 2 yards 1 × 3 feet 1 yard × 12 inches 1 foot Step 4: Notice which units have both a top and bottom component. You can cancel these units out. If you set up the conversions correctly then you should only have one unit remaining. Step 5: Calculate your final value by multiply the fractions together. To multiply fractions multiply all the top numbers together and then the entire bottom numbers together. Simplify if necessary. 2 × 3 × 12 1 × 1 × 1 inches = 72 1 inches = 72 inches Solution: 2 yards is equal to 72 inches. 5.1.2 Metric Units The metric system, which is used by most of the world, and frequently in the science fields, uses units based on multiples of ten.
