About CupOrGram
CupOrGram exists because a cup of flour and a cup of honey are completely different things. Most online converters treat all ingredients the same — we don't.
Density-Accurate
Every conversion is anchored on King Arthur Baking and USDA density data, then cross-checked against in-house bench tests.
Science-Backed Substitutions
Every substitution includes the chemistry behind why it works, so you understand what you're changing.
Why weight matters
A cup of flour can weigh anywhere from 120g to 155g depending on how you scoop it. That's a 30% variance — enough to make the difference between a perfect cake and a dry brick. Professional bakers weigh everything for a reason.
CupOrGram bridges the gap between volume-based recipes (most home cooking) and weight-based precision (professional baking). Every ingredient in our database includes its real density, tested substitutions, storage tips, and the baking science you need to understand your ingredients.
Editorial Transparency
Every ingredient's density and substitution ratios are cross-checked against published baking references — King Arthur Baking and USDA FoodData Central — and verified with in-house bench measurements before publication. Sources are listed transparently in our methodology.
