Steel-cut oats, Cups to Grams & Grams to Cups
1 cup of steel-cut oats = 176 grams · 100g = 0.57 cups
Steel-cut (Irish) oats are whole groats chopped into chunks rather than rolled, so they are dense and weigh about 176 grams per cup — nearly double rolled oats. They cook slowly into a chewy, nutty porridge. Because they are so much denser, recipes for the two are not interchangeable by volume.

How to measure steel-cut oats accurately
For the most reliable baking results, weigh steel-cut oats on a kitchen scale rather than scooping by volume. One US cup of steel-cut oats weighs about 176 grams (6.21 oz), but the exact figure changes with how tightly it's packed and the brand. Scooping straight from the bag compacts steel-cut oats and can leave you 15 to 20% over, so spoon it into the cup and level it off for the closest match to the figures above. Use the tables for quick reference, or the converter for any custom amount in cups, grams, ounces or tablespoons.
Tip: Don't swap steel-cut for rolled oats cup-for-cup — steel-cut are far denser and take much longer to cook. Use about half the volume if substituting by weight.
