Convert Cups to Grams: Active Dry Yeast
Convert cups of active dry yeast to grams with this complete reference table. 1 cup of active dry yeast = 136g (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 active dry yeast density can vary by measuring technique.
Active Dry Yeast Cups to Grams Table
| Cups | Grams |
|---|---|
| 1/8 cup | 17g |
| 1/4 cup | 34g |
| 1/3 cup | 45.3g |
| 1/2 cup | 68g |
| 2/3 cup | 90.7g |
| 3/4 cup | 102g |
| 1 cup | 136g |
| 1 1/4 cups | 170g |
| 1 1/2 cups | 204g |
| 2 cups | 272g |
| 3 cups | 408g |
| 4 cups | 544g |
Based on USDA FoodData Central data (1 US cup = 240ml = 16 tablespoons = 48 teaspoons). Note: Active dry yeast: 1 packet (2.25 tsp) = 7g. Instant yeast weighs about the same per volume. 1 tablespoon = 8.5g. Yeast granules are irregular — this is an average. Standard packet is 1/4 oz = 7g.
About Active Dry Yeast Density
The density of active dry yeast determines how much it weighs per unit of volume. At 0.567g/ml, 1 US cup (240ml) of active dry yeast weighs 136g 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 active dry yeast?
1 cup of active dry yeast weighs 136 grams (USDA FoodData Central, spooned-and-leveled method, 1 US cup = 240ml).
How many grams is 1/2 cup of active dry yeast?
1/2 cup of active dry yeast weighs 68 grams.
How many grams is 1/4 cup of active dry yeast?
1/4 cup of active dry yeast weighs 34 grams.
Does measuring technique affect the weight of active dry yeast?
Yes. Sifted active dry yeast can weigh up to 20% less than packed or scooped. The USDA standard (spooned-and-leveled) of 136g/cup is the most reliable baseline.
