A metric cup (250 ml, used in Australia, New Zealand, Canada and many Indian recipes) holds about 6% more than a US cup.
Small amounts are measured with level measuring spoons; for spices a tiny weighing error matters little, but for salt and leaveners use level spoons.
One level teaspoon is 4 g. Recipes rarely use more than a few teaspoons.
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 baking powder weighs about 192 g (6.8 oz). A 250 ml metric cup weighs about 203 g.
1 level tablespoon of baking powder is about 12 g, and 1 teaspoon is about 4 g.
100 g of baking powder is about 0.52 cups, or 8.3 tablespoons.
A cup measures volume, not weight. Baking Powder is full of air between the particles, so a cup weighs much less than a cup of water (192 g vs 237 g).
