Measuring 100g of Old-Fashioned Rolled Oats in the Kitchen
Because 1 US Customary Cup (236.6 mL) of old-fashioned rolled oats weighs 90g when measured dip and sweep, 100 Grams (100g) translates to 1.11 US cups (1 ⅛ cups).
Without a kitchen scale, measure 1 ⅛ cups (17.78 tablespoons total) using dip and sweep technique. Spoon rolled oats gently into a dry measuring cup until heaping, then sweep level with a straight edge. Shaking or tapping the cup settles the broad, flat oat flakes into trapped gaps, increasing cup weight to nearly 100 grams.
