The volume converter handles any amount between cups, tablespoons, teaspoons, and millilitres. Teaspoons to cups
Why does a cup of flour vary in weight?
Flour compresses easily, so how you fill the cup changes the weight. Spooned lightly and levelled, a metric cup of plain flour is about 140 grams. Sifted first it can fall to around 125 grams, while scooping straight from the bag and packing it down can push it to 160 grams. For consistent baking, weigh flour on a scale rather than measuring by cup.
