Cups are most often used to measure volumes of solid ingredients like flour, sugar, rice, etc. For liquids, fluid ounces are more common. However, cups can also be used to measure volumes of liquid ingredients especially in recipes.

## The Relationship Between Cups and Fluid Ounces

Since a US pint contains 16 fluid ounces, and there are 2 cups in a pint, there is a direct relationship between cups and fluid ounces:

• 1 cup = 8 fluid ounces
• 2 cups = 16 fluid ounces

This relationship allows easy conversion between cups and fluid ounces. Some key equivalents are:

Cups Fluid Ounces
1 cup 8 fl oz
2 cups 16 fl oz
1⁄2 cup 4 fl oz
1 1⁄2 cups 12 fl oz

## Examples of 16 Ounces and 2 Cups

## Measuring 16 Ounces vs. 2 Cups Accurately

To accurately measure out 16 fluid ounces or 2 cups:

• For fluid ounces, use a measuring cup designed for liquids that has ounce markings
• For cups, use a standard dry measuring cup and fill to the 2 cup line
• When measuring viscous liquids like honey or oil, measuring cups designed for liquids will be more accurate than regular dry cups
• Try to read measurements at eye level to get the most accurate measurement
• When doubling recipes, you can measure out 16 ounces or 2 cups interchangeably

## How Weight and Volume Differ

It’s important to understand that weight and volume are different units. While 16 fluid ounces is equivalent to 2 cups in volume, the weight can vary depending on the density of the liquid:

• 16 oz of water weighs about 1 pound
• But 16 oz of honey weighs about 1.4 pounds because it is denser
• When substituting in recipes, pay attention to whether volumes or weights are listed

## Common Situations Where 16 oz = 2 Cups

Knowing that 16 ounces = 2 cups is useful in many everyday cooking and baking situations:

• Doubling ingredient amounts in recipes
• Converting between fluid ounces and cup measurements in recipes
• Figuring out if you have enough of an ingredient
• Comparing nutritional information on labels
• Calculating liquid capacities of containers
• Portioning out beverages like juice, milk, cocktails

## Cooking Conversions Where 16 oz = 2 cups

Here are some specific examples of recipe conversions using the relationship between 16 ounces and 2 cups:

• A recipe calls for 1 cup milk, but you only have a 16 oz bottle. You have enough for 2 cups so can use it.
