Measuring Whole Milk Accurately
Why weight matters: 1/2 cup of whole milk can weigh anywhere from 104g to 146g depending on how you measure it. The USDA standard is 122g (spooned and leveled). Scooping directly from the container can add 10–20% extra weight, which affects recipe results — especially in baking.
About whole milk density: Whole milk is slightly denser than water. 1 cup (240ml) = 244g. The fat content (3.25%) barely affects density. For baking, 1 cup milk = 240ml = 244g. Most recipes assume whole milk unless specified.
About 1/2 Cup as a Measurement
1/2 cup (120ml) is the most common single-serving measurement in baking. It equals 8 tablespoons or 24 teaspoons. Most standard muffin recipes call for 1/2 cup of flour per 6 muffins.
Half cup is a standard baking unit used in muffins, quick breads, pancakes, and cookie doughs. It represents exactly half of a US standard measuring cup (240ml).
