Yeast Grams to Teaspoons Converter

How the yeast conversion works

The converter applies teaspoons = grams ÷ grams-per-teaspoon, and the divisor changes with the yeast in your jar. Active dry yeast is dried into comparatively coarse granules and lands at roughly 3.1 g per level teaspoon; instant yeast is milled finer, absorbs liquid faster, and settles a fraction lighter at roughly 3.0 g per teaspoon. A tenth of a gram sounds like nothing, but spoon measures compound it — across a tablespoon the gap is 0.3 g, and in a small enriched dough that is enough to nudge the rise.

Worked example: the standard 7 g packet of active dry yeast is 7 ÷ 3.1 = 2.3 teaspoons — the familiar 2¼-teaspoon measure, which is how the packet size was defined in the first place. Going the other way, a recipe written as 3 teaspoons of instant yeast needs 3 × 3.0 = 9 g from the scale.

Quick reference

• ½ tsp yeast — 1.6 g active dry · 1.5 g instant
• 1 tsp yeast — 3.1 g active dry · 3 g instant
• 2¼ tsp yeast (1 packet) — 7 g, either type
• 1 tbsp yeast — 9.3 g active dry · 9 g instant

Fresh (compressed) yeast is deliberately not a preset here: it is moist, sold in blocks by weight, and crumbles rather than spoons — weigh it, and use our yeast conversion chart when a recipe swaps fresh for dry.
