1 cup of butter in grams

One level US cup (240 ml) of butter weighs about 227 grams. That makes ½ cup ≈ 114 g, ⅓ cup ≈ 76 g and ¼ cup ≈ 57 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.
