4. Reading a Measuring Cup   Most measuring cups have two scales on them. It is normally labeled in cups and ounces. The side marked in cups is labeled with fractions.  Dry foods are measured using cups.  Ounces measure liquids.  A measuring cup is mostly used when baking or cooking food. If an ingredient is not measured accurately, the food can turn out wrong or even burnt. A shows 1 3/4 cups=14 ounces B shows1 cup = 8 ounces C shows1/2 cup=4 ounces

5. Conversion Chart MEASURES OF CAPACITY cup (c.)=8 fluid ounces (fl. oz.) cup (c.)=8 fluid ounces (fl. oz.) 1 pint (pt.)=2 cups (c.)1 pint (pt.)=2 cups (c.) 1 quart (qt.)=4 cups (c.)1 quart (qt.)=4 cups (c.) 1 quart (qt.)=2 pints (pt.)1 quart (qt.)=2 pints (pt.) 1 gallon (gal.)=4 quarts (qt.)1 gallon (gal.)=4 quarts (qt.)  When converting any unit of measurements if you want:  To change to a larger unit, divide.  To change to a smaller unit, multiply.
