1.23 US cups

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. In kitchen measures that is just under 1 1/4 cups.

How 100 grams of rolled oats was converted to cups

cups = grams ÷ grams in one US cup

A cup is a volume, so its weight depends on the ingredient. One US cup of rolled oats weighs 81 grams (eighty-one), so divide 100 by 81.

100 g ÷ 81 g

1.23 cups

(one point two three cups)

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 grams in a cup

This page starts from grams and answers in cups. The opposite question — how many grams a recipe’s cups weigh, fractions like 1/2 and 2 1/2 included — is what the cups to grams converter is for. Both read the same USDA weights, so their numbers agree: one US cup of rolled oats is 81 grams there and here.
