How to measure 30 grams without a scale
For flour and other powders, spoon the ingredient into a dry cup and level it off. For 30 g of flour that means filling cups to about ¼ cup, or 3 ⅞ level tablespoons. For liquids like water or milk, 30 g is close to 30 ml, so a measuring jug works well.
Example: 30 g flour ÷ 125 g = 0.24 cups
