How this works
Butter has a density of about 0.959 g/mL (standard: 1 cup = 227g). That means 1 mL of butter weighs 0.959 grams.
Ounces = tablespoons × 0.5002
Note: Salted or unsalted; same density. 1 stick = 1/2 cup = 113g.
Why a cup of butter doesn't always weigh the same
Volume measurements are forgiving in some ways and brutal in others. A cup of butter can vary by 10-20% in weight depending on how it's measured: spooned vs scooped, packed vs loose, sifted vs unsifted. The density figure used here matches the most common published recipe conventions, but if you're after baking precision, weighing on a kitchen scale is more accurate than measuring by volume.
