Yeast (active dry): Grams to Cups
1 cup of yeast (active dry) = 135 grams
One US cup of yeast (active dry) weighs 135 grams. One 250 ml metric cup — the one used in the UK, Australia, New Zealand and Canada — holds 143 grams. To convert any weight, divide the grams by the figure for your cup.
Active dry yeast is used by the teaspoon, not the cup. This site's working figure of 135 g per cup works out to about 2.8 g per teaspoon; a standard ¼ oz packet is 7 g, or about 2¼ teaspoons. It is an estimate, not a published reference — weigh yeast for bread.
Where the 135 g figure comes from
Neither USDA FoodData Central nor King Arthur Baking publishes a cup weight for yeast (active dry), so 135 g is this site's working estimate. Weigh it when the result matters.
