Conversion Formula

The formula to convert ounces to cups is simple: number of ounces divided by 8. Since a cup holds 8 ounces, dividing the total ounces by 8 yields the equivalent in cups. For example, if you have 24 oz, then 24 ÷ 8 = 3 cups. It works because of the fixed relationship between these units.

Conversion Example

  • Convert 36 oz to cups:
    • Step 1: Take the ounces (36 oz).
    • Step 2: Divide by 8 (since 1 cup = 8 oz).
    • Step 3: 36 ÷ 8 = 4.5 cups.
  • Convert 16 oz to cups:
    • Step 1: Ounces = 16.
    • Step 2: 16 ÷ 8 = 2 cups.
  • Convert 50 oz to cups:
    • Step 1: Ounces = 50.
    • Step 2: 50 ÷ 8 = 6.25 cups.

Conversion Definitions

oz

Conversion FAQs

How accurate is converting 28 oz to cups using dividing by 8?

This method is accurate for liquids because it relies on the fixed volume of a cup to 8 fluid ounces. However, for dry ingredients, the weight-to-volume ratio varies based on ingredient density, so conversions may slightly differ.

Can I use the same conversion for both liquids and dry ingredients?

No, because volume and weight relationships differ. For liquids, 8 oz equals 1 cup, but for dry items like flour or sugar, the weight per cup varies, making precise conversions depend on the ingredient’s density.

What if my ingredient’s weight per cup differs from standard measurements?

If your ingredient’s density differs, then converting based on weight or volume requires more specific data. Using a kitchen scale for dry ingredients ensures accuracy over simple oz to cups conversions.

Is there a difference between US cups and other cup measurements globally?

Yes, US cups are standardized at 8 fluid ounces, whereas other countries may use different cup sizes, which affects conversions. Always check the measurement standards specific to your recipe’s origin.
