Butter
Metric Cup to Gram
Understanding Butter Conversions
The Math Behind This Conversion
To convert 1 metric cup of butter to gram, we use the density of butter (0.96 g/ml). A metric cup contains 250ml, so 1 metric cup equals 250ml. Multiplying by the density: 250ml × 0.96 g/ml = 240g.
US vs Metric Cups: Why It Matters
When converting butter, the cup size matters significantly. A US cup (236.6ml) of butter weighs 227g, while a metric cup (250ml) weighs 240g—a difference of 13g (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
Butter is easiest to measure using the wrapper markings (if available) or by the displacement method: fill a 2-cup measure with 1 cup of water, then add butter until the water reaches your desired total. For example, for ½ cup butter, add butter until the water reaches 1½ cups.
About Our Data
The density value of 0.96 g/ml for butter is from the USDA FoodData Central database (ID: 173410). This measurement was taken with butter firmly packed into the measuring cup.
