King Arthur lists Yeast (instant) at 2 teaspoons = 6g; the cup figure is a transparent 48× normalization for bulk reference only, not a direct cup listing.

Ingredient questions

Instant yeast FAQ.

How many grams are in a cup of instant yeast?

King Arthur's chart lists 6g for 2 teaspoons of instant yeast, not an explicit cup. PantryGauge does not pretend that is a direct cup record: the 144g-per-cup figure is only the exact bulk normalization of that spoon reference, and is not recommended for recipe measuring.

Can I substitute active dry yeast for instant yeast?

Often, but follow the recipe or package directions because activation and quantity guidance can differ. The reference used on this page is a dry-yeast bulk approximation, not a substitution rule.

What is the practical way to measure yeast?

Use the packet's gram weight or level teaspoons. Weighing is preferable when scaling a dough.
