Water: cups to grams
A US cup of water is 236.6 mL and weighs 236.6 g, which is why grams and millilitres are interchangeable for water and nearly so for milk, juice and stock. The metric cup used in Australia and many European cookbooks is 250 mL, 6 % larger; the UK "cup" of old recipes is 284 mL.
1 cup water = 237 g · 1 tbsp = 14.8 g · 100 g = 0.42 cups
Based on 237 g per US cup of water, spooned and levelled. Real-world cups vary by about ±10 % for powders.
How to measure water
Any liquid cup works; a scale is exact. 1 tablespoon = 14.8 g (15 mL), 1 teaspoon = 4.9 g, 1 fluid ounce = 29.6 g.
Weight is the only measure that does not depend on the container or on how the ingredient was filled. The figure of 237 g per US cup comes from USDA FoodData Central; other charts differ by a few percent, which is within the spread between two cooks filling the same cup.
