Milk
US Cup to Gram
Understanding Milk Conversions
The Math Behind This Conversion
To convert 1 us cup of milk to gram, we use the density of milk (1.03 g/ml). A us cup contains 236.59ml, so 1 us cup equals 236.59ml. Multiplying by the density: 236.59ml × 1.03 g/ml = 243.7g.
US vs Metric Cups: Why It Matters
When converting milk, the cup size matters significantly. A US cup (236.6ml) of milk weighs 244g, while a metric cup (250ml) weighs 258g—a difference of 14g (6%). If you're following a recipe from a different country, using the wrong cup size could affect your results. American recipes use US cups, while recipes from Australia, UK, and most other countries use metric cups.
Measurement Tip
For room-temperature recipes, let milk sit out for 15-20 minutes before measuring. Cold milk is slightly denser than room-temperature milk, which can affect very precise recipes. Our density of 1.03 g/ml is based on refrigerated milk.
About Our Data
The density value of 1.03 g/ml for milk is from the USDA FoodData Central database (ID: 171265). This measurement was taken with milk poured into the measuring cup.
