Granulated Sugar: Cups to Grams

Estimate the weight of granulated white sugar from a published cup portion, or convert a weight back to that portion.

Check the sugar name first

The selected record is King Arthur Baking’s granulated white sugar entry. Its chart treats packed brown sugar, confectioners’ sugar, and superfine sugar as separate entries. Source: King Arthur Baking ingredient weight chart.

Use this estimate only when that description fits. A recipe calling for another sugar needs the relevant food record; changing the name does not make this portion applicable.

Work from the recipe’s own weight when you can

If the recipe includes grams, use those grams directly. If it only gives cups, this source portion provides a clearly identified estimate. The tool scales the source portion proportionally rather than averaging several charts.

A source cup here has no confirmed milliliter capacity. That is why this ingredient calculation does not offer a switch to a different country’s cup standard.

Keep a useful recipe note

Save the ingredient name and source along with the converted amount. If a later batch uses a different sugar, that note makes the assumption visible instead of leaving you with an unexplained number.

Compare another ingredient in cups to grams, or read our method for source portions and estimates.
