1 Cup of Flour in Grams and Ounces
1 cup of all-purpose flour weighs 120 grams, or 4.2 ounces. That is for flour spooned into the cup and leveled off, the standard used by most US recipes.
Weigh it if you can. A kitchen scale gives the same result every time, and cups do not.

Why your cup might weigh more
Scooping the cup straight into the bag packs the flour down, and a scooped cup can weigh 10 to 20 grams more than a spooned one. Over 3 cups that is enough to make cookies dry and cakes dense. Spoon the flour into the cup, level it with a knife, or skip cups and weigh it.
