Understanding Ounces vs. Cups

Before we jump into numbers, it’s important to know that ounces (oz) can mean two different things:

• Fluid ounces (fl oz) measure volume — used for liquids like milk or water.
• Dry ounces (oz) measure weight — used for solids like flour or sugar.

That means 8 oz of water is not always the same as 8 oz of flour. Using the SmartUnitCalculator Ounces to Cups Converter, you can convert either type accurately.

How Many Ounces Are in a Cup?

Let’s start with the basic conversion:

• 1 U.S. cup = 8 fluid ounces (fl oz)
• 1 fluid ounce = 1/8 cup

Measurement	Cups	Fluid Ounces (fl oz)
1 Cup	1	8 fl oz
1/2 Cup	0.5	4 fl oz
1/4 Cup	0.25	2 fl oz
3/4 Cup	0.75	6 fl oz
2 Cups	2	16 fl oz

So, when converting oz to cups:

• 8 oz = 1 cup
• 16 oz = 2 cups
• 4 oz = 1/2 cup
• 2 oz = 1/4 cup

Dry vs. Liquid Ounce to Cup Conversion

For liquids, conversions are straightforward. But for dry ingredients, density matters. For example:

Ingredient	1 Cup Equals	1 Ounce Equals
All-purpose flour	120g	0.13 cups
Granulated sugar	200g	0.1 cups
Butter	227g	0.125 cups
Honey	340g	0.09 cups
Rice (uncooked)	185g	0.12 cups

💡 Tip: Always check if your recipe uses weight ounces (oz) or fluid ounces (fl oz).

If you’re unsure, use the SmartUnitCalculator Ounces to Cups Converter — it calculates both types precisely.
