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 uses the ingredient's real density from NIST-standardized data. No rounding, no guessing.
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
CupOrGram pages are reviewed by the CupOrGram Editorial Team and built from density-based references plus recipe-testing notes. We also keep thin template combinations out of index coverage until expanded.
