Where this number comes from
Most of our weights are the King Arthur Baking chart figure, unchanged. This one is not, and it is worth saying why: From King Arthur's own chart row for one packet, 2¼ tsp = 7 g: that is 3.11 g per tsp, or 149 g per cup. The chart's 1 tbsp = 9 g row rounds lower (144 g a cup); we use the packet row so this page matches the yeast converter.
Every value we don't depart on is locked to the chart by a test, and each departure is pinned to the publication it names, so this list stays short and deliberate — you can read all of them on the methodology page.
