Measurement notes

  • Granulated sugar pours and settles fairly consistently, so cup measurements are more reliable than flour.
  • Spoon sugar into the measuring cup and level off the top with a knife for consistent results.
  • Superfine (caster) sugar weighs slightly less per cup than standard granulated sugar in King Arthur's weight chart, so this value is for granulated sugar only.
  • A kitchen scale removes any guesswork when a recipe needs precise sugar amounts.

Sources & how they compare

The adopted value and every comparison below come from the site's versioned ingredient dataset.

Measuring step this site recommends: spooned level.

When sources disagree, follow your recipe: use its gram weights if it gives them, or measure the way its author did. The adopted value is one stated convention, not a correction of the other sources.

A comparable source-cup value only scales a half-cup or tablespoon serving to one source cup. When a source does not state the cup's exact volume, we do not present it as a fixed-milliliter normalization.
