API, OpenAPI and WebMCP documentation

Explanation

Calculation basis: grams per US cup divided by 8 US fluid ounces per cup.

Oatmeal uses a recorded reference of 90 grams per US cup in this dataset. Confidence: low. Source basis: and1 ingredient weight chart: 1 cup oatmeal = 90 g https://www.and1.com/measurements/cups-in-gram/

Evidence status: source-unverified. The cited AND1 source has not been independently verified. Its current domain context does not establish the original measurement. Particle size, aeration, settling, and whether the cup is scooped or spoon-filled can materially change the mass held by the same volume.

Questions & answers

Frequently Asked Questions

Is this based on an ingredient-specific density estimate?

Yes. The page reduces the same 90 g-per-cup basis to a per-fluid-ounce estimate for Oatmeal.

Does grain shape or settling change the result for Oatmeal?

Oatmeal keeps one reference basis here, but grain shape and how the grains settle in the cup can shift practical density. That is why volume estimates for this ingredient should stay ingredient-specific.
