Answer
One US cup (236.6 ml) of rolled oats weighs 81 grams, from USDA FoodData Central, SR Legacy entry 173904 “Cereals, oats, regular and quick, not fortified, dry”, portion “1 cup” = 81 grams.

The weight of the cup comes from USDA FoodData Central, SR Legacy entry 173904 “Cereals, oats, regular and quick, not fortified, dry”, portion “1 cup” = 81 grams. Scooped ingredients vary with how they are filled — spooned in lightly, a cup weighs less; packed down, more — so for baking a kitchen scale is the exact tool and this figure the standard reference.

The other way round: how many cups a weight fills
This page starts from cups and answers in grams. The opposite question — how many cups a weight from a recipe fills — is what the grams to cups converter is for. Both read the same USDA weights, so their numbers agree: 100 grams of rolled oats is 1.23 cups there.
