Conversions: Metric, Apothecary, and Household System Converting from one unit to another using the conversion factor method  Recall the equivalents  Multiply or divide Rule to convert from a larger to a smaller unit measurement, multiply by the conversion factor. Think: “Larger is going down to smaller, so you will multiply.” Larger↓ Smaller→ Multiply (X) Example: How many cups are in 3 quart? You know that 1 quart =4 cups. Cups are smaller than quarts. THINK: LARGER↓SMALLER→MULTIPLY(X) The conversion Factor is 4 cups /1 quart Multiply by the conversion factor Quarts (larger unit) X conversion factor (cups/qt) = cups (smaller unit) 3 qt X 4 cups/qt = 12 cups Rule to convert from a smaller to a larger unit of measurement, divide by the conversion factor. THINK: “Smaller is going to larger, so you will divide.” Smaller ↑ Larger → Divide ( ) Example: How many quarts are in 8 cups? You know that 1 qt= 4 cups. The conversion factor is 4 cups/1 quart. Quarts are larger than cups. Divide by the conversion factor because it takes fewer of the quart unit to equal the same amount of the cup unit. THINK: SMALLER ↑LARGER → Divide 8 cups 4 cups/qt = 2 qtDosage Calculation Review Study Booklet-NUR 101-Bishop State Community CDosage Calculation Review Study Booklet-NUR 101-Bishop State Community College.p
