Measuring step this site recommends: firmly packed.

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.

Measurement notes

  • Brown sugar must be firmly packed into the measuring cup — packed versus loose can change the weight by a large margin.
  • It should hold the shape of the cup when turned out, which confirms it was packed correctly.
  • Light and dark brown sugar have nearly the same density, since the difference is mostly molasses color and flavor, not weight.
  • Brown sugar hardens when exposed to air, so measure it soon after opening for a more consistent result.

Common mistakes

  • Assuming 1 cup of brown sugar (packed) equals 240g like water — it is actually 220g per US cup.
  • Assuming every type of sugar (granulated, brown, powdered) weighs the same per cup.

Can I convert cups of brown sugar (packed) back to grams?

Yes, use the Cups to Grams tool with brown sugar (packed) selected to convert any cup amount back into grams.

Why does brown sugar (packed) convert differently from other ingredients?

Grams measure weight and cups measure volume, so the conversion depends on how dense brown sugar (packed) is. A denser or lighter ingredient weighs a different amount per cup.
