What is long-grain white rice (dry)?

This record deliberately narrows “rice” to uncooked, dry, long-grain white rice. Long-grain rice usually cooks into more separate grains than short-grain rice, while brown, parboiled, and aromatic varieties have different structures and cooking behavior.

Keep dry rice sealed against moisture and pests. Pour the grains loosely into the cup and level without tapping; the adopted reference is about 185 grams per US cup. Rinsed, soaked, or cooked rice needs a different measurement.

Why measurements vary

Grain shape and settling

Long, short, broken, and parboiled grains leave different air spaces when poured into a cup.

Dry versus cooked state

Rinsing, soaking, and cooking add variable water, so prepared rice cannot use the dry-rice reference.

How to measure long-grain white rice (dry)

poured loosely and leveled

  • 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.

Frequently asked questions

How many grams are in 1 cup of dry rice?

1 source cup of loose, uncooked long-grain white rice is about 185 grams under the adopted USDA reference.

Does this number work for cooked rice?

No. Cooking adds a variable amount of water, so cooked rice is a different ingredient state and density.

Why does rice variety matter in cooking?

Grain shape and starch composition affect how rice absorbs water and whether it cooks fluffy, firm, or sticky. Long-grain white rice is only one of several distinct rice types.

How should dry rice be stored?

Keep it sealed in a cool, dry place away from moisture and pantry pests. Do not rinse it until the recipe is ready to be cooked.
