Reporting a conversion or website issue?

Please include the ingredient, amount, conversion direction and cup setting you used. Tell us the result shown and what you expected instead. You can add the page address in the form and include a source link in your message.

For a display or button problem, include your device and browser if you know them.

A different result does not always mean a calculation is wrong. Ingredient preparation, cup size and published reference weights can differ. Our grams-per-cup chart lists the references used, and our methodology explains the calculations.

Suggest an ingredient or improvement

Tell us which ingredient or feature would help you and how you would use it. For ingredient requests, be specific about the type and preparation—for example, cooked rice rather than dry rice. A published weight reference is helpful if you have one.
