Measuring 120g of Whole Milk in the Kitchen

Because 1 US Customary Cup (236.6 mL) of whole milk weighs 240g when measured poured liquid, 120 Grams (120g) translates to 0.50 US cups (½ cup). By contrast, using the nonfat / skim milk measure (245g/cup — a 5g per-cup shift), 120g occupies ½ cup (0.49 cups).

Without a kitchen scale, measure ½ cup (8 tablespoons total) using poured liquid technique. Pour into a liquid measuring cup set on a level counter and read the bottom of the meniscus at eye level.

Frequently Asked Questions

How many cups is 120 grams of whole milk? ▾

120 grams of whole milk (poured liquid, 240g per US cup) equals ½ cup (0.50 US Customary Cups, 0.47 Metric 250 mL cups, or 8 tablespoons).

Why does 1 cup of whole milk weigh 240g while water weighs 236.6g? ▾

Milk contains dissolved sugars (lactose), proteins (casein, whey), and emulsified fat globules, giving it a higher specific gravity (~1.03).

Does scalded milk make bread dough rise better? ▾

Yes, heating milk to 180°F denatures whey proteins that can otherwise weaken the gluten structure in yeast breads.
