How to convert ounces of rolled oats to cups
Weight ounces first become grams (1 oz = 28.35 g), so 4 oz = 113 g. One US cup of rolled oats weighs 90 g, so 113 ÷ 90 = 1.26 cups.
Grains settle when shaken, so pour them in loosely and level off rather than tapping the cup.

Slightly. UK, Australian and New Zealand recipes use a 250 ml metric cup, which is about 6% bigger than a US cup (236.6 ml). In metric cups, 4 ounces of rolled oats is 1.19 cups.
