1 cup of milk in grams

One level US cup (240 ml) of milk weighs about 240 grams. That makes ½ cup ≈ 120 g, ⅓ cup ≈ 80 g and ¼ cup ≈ 60 g. These are scoop-and-level averages — packing the cup can add up to 20%, which is why bakers swear by a scale. More ingredients in the full cups-to-grams converter.
