How to Convert 30 Grams to Cups

To convert grams to cups, divide the gram amount by the ingredient’s grams-per-cup value. Cups measure volume and grams measure weight, so a heavier ingredient such as honey or butter fills a cup differently than flour or oats.

Measuring Tips

Use a kitchen scale whenever precision matters.
For flour, spoon into the cup and level off instead of scooping.
For packed sugars, match the recipe’s instruction exactly.
