Formula and Step-by-Step

cups × 227g/cup = grams
  1. Start with 0.81 cups of butter
  2. 1 cup of butter = 227g
  3. 0.81 × 227 = 183.87g

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

Measuring Tip

Butter is easiest to measure using the markings on the wrapper. One US stick = 113g = 1/2 cup = 8 tablespoons.

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 a Gram?

Weighing ingredients in grams eliminates the variability of volume measurements. A cup of flour can weigh anywhere from 120g to 160g depending on how it was scooped, but 120g of flour is always 120g of flour.

Frequently Asked Questions

About 183.87 g, 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). For 0.81 cups: 0.81 × 227 = 183.87 g.
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: 183.87 g ÷ 227 = 0.81 cups. Or use the Grams to Cups converter.
