The Science of a Gram
Every ingredient has a unique density. A cup of flour can weigh between 120g and 155g depending on how you scoop it — a 30% variance that can ruin a recipe. Our conversions are anchored on King Arthur Baking and USDA FoodData Central, cross-checked against our own bench tests. Pick your cup size — US, Metric, or Imperial — and the maths follows.
