Method and assumptions
Grams and ounces measure mass. A US stick is four ounces, about 113.4 g; a US wrapper cup is two sticks, about 227 g. A European retail pack may have another weight.
Wrapper tablespoon marks are a packaging convention. They do not establish the physical density of melted or whipped butter. Use a measured density for the 15 mL spoon mode and replace the editable starting assumption.
Enter your actual package weight. Keep the original grams when possible and print the selected measure and assumptions with the result.
