Why weight beats volume for instant yeast
A cup is a volume; a recipe cares about mass. Instant yeast runs about 149 g per US cup measured spoon-and-level, but packing, humidity, and grind can move that by ±10%. Weighing removes the guesswork, which is exactly why serious baking recipes list grams.
A standard 7 g packet is 2¼ teaspoons.
