About this site

Who runs this site

Stefan Ulrich maintains gramsinacup.com, a reference for converting baking ingredients between US cups and grams.

What the converter can tell you

The same cup holds different weights of flour, sugar or honey. Each ingredient page explains the form used for its reference value and the details that matter when measuring. The recipe converter helps apply those references to a list of ingredients.

Where the values come from

The source note on each ingredient page records a comparison with a named published reference, a difference between references, or a value that has not yet been independently matched. A source link is a comparison, not an endorsement or proof of measurements in our kitchen. The existing values were reviewed against sources in September 2026; some remain estimates or differ from the cited table.

Editorial process

The site uses AI-assisted writing and translation. In this review, ingredient-specific instructions and arithmetic were checked, generic text was replaced, and source differences were recorded. This is a review of published references, not a claim of original laboratory or kitchen measurements. The translations have not received independent native-speaker certification.

How to use the values

Our converters use a US cup of approximately 236.6 ml. A metric 250 ml cup and an ordinary drinking cup are different measures. Grams are rounded for display. Packing, chopping, draining and product formulation can change the amount in a cup. If the recipe author provides grams, use those instead of converting again.
