Reporting a conversion error
To help us check quickly, include:
- The page address (URL).
- The number you think is wrong.
- Where your figure comes from, for example the package, a recipe or another reference.
Every weight on the site comes from one list, so a correction fixes it everywhere at once. You can see the current figures and their sources on how we calculate.
Suggesting an ingredient
Tell us the ingredient and, if you know it, the brand or type. We add ingredients when we can find a reliable published weight per cup.
