A metric cup (250 ml, used in Australia, New Zealand, Canada and many Indian recipes) holds about 6% more than a US cup.
Spoon the flour into the cup and level it with a knife. Scooping straight from the bag packs it down and can add 20–30% more.
Potato starch is much heavier than potato flour (about 184 g per cup).
Weights are for a level US cup (236.6 ml) and level spoons, from King Arthur Baking's ingredient weight chart. Brands and packing vary by a few per cent; when a recipe gives grams, weigh rather than measure.
1 level US cup of potato starch weighs about 152 g (5.4 oz). A 250 ml metric cup weighs about 161 g.
1 level tablespoon of potato starch is about 9.5 g, and 1 teaspoon is about 3.2 g.
100 g of potato starch is about 0.66 cups, or 10.5 tablespoons.
A cup measures volume, not weight. Potato Starch is full of air between the particles, so a cup weighs much less than a cup of water (152 g vs 237 g).
