Cups of Rice to Grams

Cups to grams — quick reference

The formula

Cups of uncooked white rice to grams is one multiply by 185 grams per cup:

grams = cups × 185

Worked example: 1 cup × 185 = 185 g; ½ cup ≈ 93 g; 2 cups = 370 g. The quick table covers ¼ through 2 cups.

This is dry, uncooked rice. Cooking absorbs water and roughly triples the weight — 1 cup dry (185 g) yields about 3 cups cooked — so never use the dry figure for cooked rice.

How to use the cups of rice to grams

A cup of uncooked white rice is 185 grams. Enter cups for grams, or swap to convert grams back to cups. The one thing to get straight first: this is raw, dry rice — cooked rice is a completely different weight.

That uncooked-versus-cooked distinction is the trap rice sets. Rice absorbs two to three times its weight in water as it cooks, so one cup of dry rice (185 g) becomes roughly three cups of cooked rice weighing around 550–600 grams. A recipe or nutrition label that says “1 cup rice” means dramatically different things depending on which side of the pot you’re on — and most cooking recipes mean uncooked, while most calorie counts and leftovers are cooked.

So when you weigh, match the state the recipe intends. If it lists dry rice, use 185 g per cup. If it’s counting cooked rice (common for portioning meals or logging nutrition), weigh after cooking instead, where a cup runs closer to 185–200 g of cooked grains because the water adds weight but the grains spread out. Mixing the two is how a side dish for four turns into a side dish for one.

Different white rices — long-grain, basmati, jasmine — land close to 185–195 g per dry cup, so the figure travels well across common varieties. Brown rice is similar dry but absorbs more water and takes longer to cook. These values use the 240 ml US cup, and the rule of thumb worth remembering is simply that cooked rice weighs about three times its dry self.
