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 use NIST-standardized density charts so you get the same result every time, whether you're in New York or New Zealand.
