How to measure 40 grams without a scale

For flour and other powders, spoon the ingredient into a dry cup and level it off. For 40 g of flour that means filling cups to about ⅓ cup, or 5 ⅛ level tablespoons. For liquids like water or milk, 40 g is close to 40 ml, so a measuring jug works well.

cups = grams ÷ grams per cup
Example: 40 g flour ÷ 125 g = 0.32 cups
