1. Section 9.6 Capacity

2. Units ofcapacityare generally used to measure liquids. The number of gallons of gasoline needed to fill a gas tank in a car, the number of cups of water needed in a bread recipe, and the number of quarts of milk sold each day at a supermarket are all examples of using units of capacity. Martin-Gay, Prealgebra, 5ed

3. U.S. Units of Capacity Unit Fractions 8 fluid ounces (fl oz) = 1 cup (c) 2 cups = 1 pint (pt) 2 pints = 1 quart (qt) 4 quarts = 1 gallon (g) Martin-Gay, Prealgebra, 5ed

4. 10 cm 10 cm 10 cm Capacity: Metric System of Measurement The liter is the basic unit of capacity in the metric system. A liter is the capacity or volume of a cube measuring 10 centimeters on each side.

5. Metric System of Measurement Prefix kilo hecto deka deci centi milli Meaning 1000 100 10 1/10 1/100 1/1000 Metric Unit of Length 1 kiloliter (kl) = 1000 liters (L) 1 hectoliter (hl) = 100 L 1 dekaliter (dal) = 10 L 1 liter (L) = 1 L 1 deciliter (dl) = 1/10 or 0.1 L 1 centiliter (cl) = 1/100 or 0.01 L 1 milliliter (ml) = 1/1000 or 0.001 L The prefixes for metric units of capacity are the same as for metric units of length and mass. Martin-Gay, Prealgebra, 5ed

6. Start End 3 units to the left 3 places to the left The two most commonly used units of capacity in the metric system are the milliliterand the liter. As with length and mass, all units of capacity are powers of 10 of the liter, so converting from one unit of capacity to another only involves moving the decimal point. kl hl dal L dl cl ml Using the listing of units of capacity, convert 5350 ml to liters. 5350 ml = 5.350 L Martin-Gay, Prealgebra, 5ed
