How this works
Milk has a density of about 1.030 g/mL (usda fooddata central). That means 1 mL of milk weighs 1.030 grams.
Cups = grams × 0.0041
Note: Whole milk. 2% is ~1.029, skim ~1.033.
Why a cup of milk doesn't always weigh the same
Volume measurements are forgiving in some ways and brutal in others. A cup of milk 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.
