Convert Cups to Grams: Whole Milk

Convert cups of whole milk to grams with this complete reference table. 1 cup of whole milk = 244g (USDA FoodData Central, spooned-and-leveled method). Use the table below for fractions from 1/8 cup up to 4 cups. For precision baking, weight measurements in grams are always more reliable than volume measurements in cups, because whole milk density can vary by measuring technique.

Based on USDA FoodData Central data (1 US cup = 240ml = 16 tablespoons = 48 teaspoons). Note: 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 Whole Milk Density

The density of whole milk determines how much it weighs per unit of volume. At 1.017g/ml, 1 US cup (240ml) of whole milk weighs 244g under USDA standard conditions.

Volume measurements can vary by ±10–20% depending on technique (sifted vs. spooned vs. scooped). For consistent baking results, use a kitchen scale with gram measurements whenever possible. The USDA standard (spooned-and-leveled) is the reference point for all values on this page.

Frequently Asked Questions

How many grams is 1 cup of whole milk?
