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.
Also called: arrowroot flour.
Weights are for a level US cup (236.6 ml) and level spoons, from USDA FoodData Central household measures. Brands and packing vary by a few per cent; when a recipe gives grams, weigh rather than measure.
1 level US cup of arrowroot powder weighs about 128 g (4.5 oz). A 250 ml metric cup weighs about 135 g.
1 level tablespoon of arrowroot powder is about 8 g, and 1 teaspoon is about 2.7 g.
100 g of arrowroot powder is about 0.78 cups, or 12.5 tablespoons.
A cup measures volume, not weight. Arrowroot Powder is full of air between the particles, so a cup weighs much less than a cup of water (128 g vs 237 g).
