Measuring step this site recommends: poured loosely and leveled.
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
- 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
- Assuming 1 cup of long-grain white rice (dry) equals 240g like water — it is actually 185g per US cup.
- Rinsing the rice before measuring it, so the wet grains bring water into the cup — measure it dry, then rinse.
