Formula and Step-by-Step

(ounces × 28.35g/oz) ÷ 227g/cup = cups

Start with 2.64 ounces of butter
Convert ounces to grams: 2.64 × 28.35 = 74.84g
1 cup of butter = 227g
74.84g ÷ 227g/cup = 0.33 cups

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Measuring Tip

Softened butter and melted butter measure differently by volume. Melted butter settles with no air pockets, giving a slightly higher weight per cup.

Understanding the Units

What is an Ounce?

Weight ounces and fluid ounces are different measurements. A fluid ounce measures volume (29.574 ml), while an ounce measures weight (28.35g). They only align for water, where 1 fl oz weighs approximately 1 oz.

What is a Cup?

There are three cup standards used worldwide. The US cup (236.588 ml) is used in American recipes. The metric cup (250 ml) is standard in Australia, New Zealand, and some parts of Asia. The imperial cup (284.131 ml) appears in older British and Canadian recipes. A metric cup holds about 5.7% more than a US cup, while an imperial cup holds about 20% more. Using the wrong standard can noticeably affect a recipe.

How do I measure butter accurately? expand_more

For the most accurate results, weigh butter on a kitchen scale. If measuring by volume, spoon the ingredient into the measuring cup and level it off with a straight edge rather than scooping directly.

Does the fat content of butter change the weight? expand_more

Fat content has a small effect on density. Higher-fat versions are slightly lighter per volume because fat is less dense than water. The difference is usually under 5%, so this conversion works well for standard varieties.

How do I convert cups of butter back to ounces? expand_more

Reverse the conversion: 0.33 cups × 227g/cup = 74.84g, then 74.84g ÷ 28.3495 = 2.64 ounces. Or use the Cups to Ounces converter.
