All-Purpose Flour: grams to cups
Many recipes outside the US list weights. Divide the grams by 120 (the typical weight of one cup) to get cups. A tablespoon is 1/16 cup, about 7.5 g, and a teaspoon is 1/3 tablespoon, about 2.5 g.

Measuring all-purpose flour by cup and by weight
A cup of all-purpose flour is 120 g only if you spoon it into the cup and level it. Dip the cup straight into the bag and it compacts to 140–150 g, which is why cookies baked from scooped flour come out dry and cakey. Sifting before measuring makes a cup lighter still, so a recipe that says "1 cup sifted flour" is asking for less flour than "1 cup flour, sifted". When a recipe lists grams, trust them over the cup.
