A cup is not the same everywhere
- Korean and Japanese recipes: 1 cup = 200 mL
- US recipes: 1 cup ≈ 236.6 mL
- Metric cup (Australia, New Zealand and others): 250 mL
- Tablespoon 15 mL and teaspoon 5 mL. The US tablespoon is about 14.8 mL, practically the same.
Converting volume to weight
Pick an ingredient to turn cups or spoons into grams. Dry ingredients vary a lot depending on whether they are sifted or packed, so the values here are typical for spooned and levelled measures. For baking, a kitchen scale is the most reliable.
