How Much Is 1.5 Cups of Butter in Grams?
1.5 cups of butter equals 340.50 g. Butter has a density of 227g per cup (227g per cup), which means it's relatively heavy compared to other common cooking ingredients. For comparison, 1.5 cups of all-purpose flour would be 187.74 g.
Formula and Step-by-Step
- Start with 1.5 cups of butter
- 1 cup of butter = 227g
- 1.5 × 227 = 340.5g
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.
