How many cups is 100 grams of water?
Answer
≈ ⅜ cup
100 grams of water fills about ⅜ cup (0.422 US cups, or about 6.75 tablespoons). The math uses USDA's figure of roughly 237 g per cup.
1 mL of water weighs very close to 1 g, which is why a cup of water is about 237 g.

Measuring tip
Liquids are the easiest thing to measure by volume, so cups and a scale will agree closely. Dairy weighs a little more or less than water depending on its fat, sugar and air content. When a recipe gives grams, a scale is always the most accurate choice.
