How Many Grams in a Cup of Rice (Long-Grain, Uncooked)?
One cup of uncooked long-grain rice weighs 185 grams. This page covers dry rice — basmati and ordinary long-grain white — because cooked rice takes on water unpredictably and no honest cup weight survives the pot. Short-grain rice is heavier at 200 grams a cup. Below are the dry-rice conversion tables, a converter, and how weighing rice makes results repeatable.

How to measure long-grain rice (uncooked) properly
Weigh it dry, before rinsing. Rinsing adds surface water and soaking adds more, so the time to weigh rice is straight from the bag. 185 grams of dry long-grain rice, cooked by absorption, serves about four as a side — and weighed dry, it does so every time.
Work the water ratio by weight. For long-grain rice cooked by absorption, about 1.5 times the rice's weight in water is the reliable starting point — roughly 278 grams of water for a 185-gram cup of rice. Volume ratios drift with the variety; weight ratios do not.
Beware the rice-cooker cup. The plastic cup bundled with rice cookers is a Japanese gō of 180 ml, not a 236.6 ml US cup — it holds about 140 grams of rice. Half the world's “my rice ratio failed” stories are this one mismatch, and weighing both rice and water ends it.
Frequently asked questions
How many grams are in a cup of uncooked rice?
185 grams for long-grain white rice, including basmati. Short-grain rice — arborio, sushi rice — is denser per cup at 200 grams. Both figures are for dry rice; once cooked, the weight per cup depends on the water absorbed.
How many grams are in a cup of cooked rice?
About 158 grams for cooked long-grain rice, but treat it as an estimate: the same rice cooked softer or firmer can sit anywhere in the 150–195 gram range. This is exactly why recipes are best weighed dry — 185 grams of dry long-grain rice gives you a known starting point.
How many grams are in half a cup of uncooked rice?
93 grams (half of 185, rounded). With the matching 139 grams or so of water by the 1-to-1.5 weight ratio, that is a side portion for two — the scale makes small batches as reliable as large ones.
