How to read this table
Grams-per-cup values are given for three cup standards — US cup (240 ml), US customary cup (236.6 ml), and metric cup (250 ml) — because the same ingredient weighs a different amount depending on which cup you use. All values are approximate: actual weight can vary by brand, grind, packing, and humidity, and by whether the ingredient is spooned, scooped, or packed into the cup.
Sources & review process
Every value starts from reviewed baking references and standard kitchen measuring conventions, and an automated check makes sure it stays in a plausible range and matches the source it was adopted from. Each entry carries a confidence rating and a last-checked date, and a value changes only when its cited source supports the change.
