Quick oats:
grams to cups.
Quick oats weigh 85 g per cup — slightly lighter than old-fashioned rolled oats (90 g) because they're cut into smaller, more irregular pieces that pack with more air gaps. The difference seems small, but it adds up in recipes like oat bars and granola.

Why quick oats are lighter than rolled oats per cup
Quick oats (also called 1-minute oats) are made from oat groats that are rolled thinner and then cut into two or three pieces before rolling. The resulting irregularly shaped fragments don't stack as uniformly as the whole-flake discs of old-fashioned oats, leaving more air spaces in the measuring cup. This is counterintuitive — you might expect smaller pieces to pack more densely — but the irregular shapes of cut oats bridge unpredictably, whereas whole disc-shaped flakes stack more consistently face-to-face. At 85 g per cup, a recipe using quick oats by volume calls for about 6% less oat mass than the same recipe using old-fashioned oats.
Texture implications for baking: cookie softness and granola clusters
Quick oats absorb liquid faster than old-fashioned oats during baking. In oatmeal cookies, this means quick oats produce a softer, more uniform texture because the oats hydrate and merge into the dough rather than remaining as distinct chewy pieces. In granola, quick oats create a sandier, less chunky texture. If you want granola clusters or hearty cookie chew, old-fashioned oats are the right choice. If you want a smoother oat presence, quick oats deliver that. The weight difference (85 g vs 90 g per cup) is secondary — the texture difference from flake size is the more important distinction between these two oat types.
