Single-conversion pages for active dry yeast

Working with active dry yeast

Active Dry Yeast sits in the leaveners, salt & spices group, where a cup lands in the same range as water, but the material still compacts differently depending on how you fill the cup. 1 packet = 2 1/4 tsp = 7 g. Instant yeast can replace it 1:1 by weight without proofing.

If you are converting a whole recipe rather than a single line, the Recipe to Metric converter matches every ingredient to its own density in one pass, and the Recipe Scaler resizes the batch first so you only convert once.
