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

  • This record is for uncooked long-grain white rice; cooked rice has absorbed water and must not use this conversion.
  • Pour the dry grains loosely into the cup and level the top without shaking.
  • Short-grain, jasmine, basmati, brown, and parboiled rice can settle differently.

Common mistakes

  • Not measuring long-grain white rice (dry) the recommended way — poured loosely and leveled — is one of the most common sources of error.
  • Assuming 1 cup of long-grain white rice (dry) equals 240g like water — it is actually 185g per US cup.
  • Pressing the cup down instead of scooping it loosely.
