Where this number comes from
The weight is taken from the USDA FoodData Central SR Legacy record "Leavening agents, yeast, baker's, active dry" (FDC ID 175043), portion "1 tsp" = 4 g. The USDA lists this ingredient by the teaspoon, so the cup figure is scaled up (48 tsp = 1 cup). US cups are 236.59 mL. A metric cup (250 mL) holds about 203 g, and a UK imperial cup (284 mL) about 231 g.
Real kitchens vary. Brand, humidity, how finely something is ground and how hard you pack the cup can all move the weight by 5–15%. If a recipe author gives grams, use their number.
