Convert Cups to Grams: Skim Milk (Non-fat)
Convert cups of skim milk (non-fat) to grams with this complete reference table. 1 cup of skim milk (non-fat) = 245g (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 skim milk (non-fat) density can vary by measuring technique.
Skim Milk (Non-fat) Cups to Grams Table
| Cups | Grams |
|---|---|
| 1/8 cup | 30.6g |
| 1/4 cup | 61.3g |
| 1/3 cup | 81.7g |
| 1/2 cup | 122.5g |
| 2/3 cup | 163.3g |
| 3/4 cup | 183.8g |
| 1 cup | 245g |
| 1 1/4 cups | 306.3g |
| 1 1/2 cups | 367.5g |
| 2 cups | 490g |
| 3 cups | 735g |
| 4 cups | 980g |
Based on USDA FoodData Central data (1 US cup = 240ml = 16 tablespoons = 48 teaspoons). Note: Skim milk is slightly denser than whole milk because fat is less dense than water. 1 cup = 245g. Nutritionally different but same volume conversion. Substitute 1:1 in most baking recipes.
About Skim Milk (Non-fat) Density
The density of skim milk (non-fat) determines how much it weighs per unit of volume. At 1.021g/ml, 1 US cup (240ml) of skim milk (non-fat) weighs 245g 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
