Counting the Amount of Fluid in Your Diet

How much can I drink in a day?
You should have ____________milliliters (mL), _______ ounces (oz), or ____ cups of liquid each day.

What do I count as fluid?
You will need to account for anything that you drink. Any food that you eat that becomes liquid at room temperature must also be counted.

How do I measure what I drink and eat?
The list below will help you convert the fluids that you are drinking into ounces (oz) and milliliters (mL).

1 tablespoon = ½ oz = 15 mL
¼ cup = 2 oz = 60mL
½ cup = 4 oz = 120mL
¾ cup = 6 oz = 180mL
1 cup = 8 oz = 240mL
12 oz can of soda = 360mL
1 liter = 1000mL
1 quart = 1060mL
4 cups = 32 oz = 1 quart = 945mL
8 cups = 64 oz = 2 quarts = 1920 mL

Water, fruit juices, milk, decaf coffee, decaf tea, herbal decaf tea, or caffeine free sodas are great sources of the fluid that you need. Caffeine and alcohol can have a mild diuretic effect. Limit the alcohol and caffeine in your diet. These drinks should be counted toward your fluid total. Talk to your doctor or a registered dietitian if you have questions about caffeine.
