How Much Is 1.45 Cups of Butter in Ounces?

1.45 cups of butter weighs 11.61 oz. This is based on butter having a density of 227g per cup. Because cups measure volume and ounces measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 1.45 cups.

Formula and Step-by-Step

cups × 227g/cup ÷ 28.3495g/oz = ounces
  1. Start with 1.45 cups of butter
  2. 1 cup of butter = 227g
  3. 1.45 × 227 = 329.15g
  4. Convert grams to ounces: 329.15 ÷ 28.3495 = 11.61 oz

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

Measuring Tip

Cold butter straight from the fridge is hardest to measure by volume. Cut it into tablespoon-sized pieces using the wrapper markings for accuracy.

Understanding the Units

What is a Cup?

In US cooking, a cup measures volume, not weight. One standard US cup holds 236.588 ml of liquid. Because different ingredients have different densities, a cup of one ingredient can weigh very differently from a cup of another.

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.

Frequently Asked Questions

About 11.61 oz, based on butter having a density of 227g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of cups by 227 (grams per cup for butter), then divide by 28.3495 to convert grams to ounces. For 1.45 cups: 1.45 × 227 = 329.15g, then 329.15 ÷ 28.3495 = 11.61 oz.
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.
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.
Reverse the conversion: 11.61 oz × 28.3495 = 329.15g, then 329.15g ÷ 227 = 1.45 cups. Or use the Ounces to Cups converter.
