White Rice: Cups to Grams
Quick answer: One US cup of uncooked white rice weighs about 185 grams (6.5 oz), and one tablespoon about 12 g.
US recipes measure uncooked white rice in cups; the rest of the world weighs it. Convert any amount in either direction — and measure it the way the chart assumes: that's uncooked — a cup of dry rice roughly triples to about 3 cups once cooked.

How it works
Cups measure volume and grams measure weight, so the conversion runs through density: uncooked white rice packs about 185 g into a US cup (237 ml). Volume is only as accurate as your technique — that's uncooked — a cup of dry rice roughly triples to about 3 cups once cooked. That variability is exactly why serious baking recipes list grams, and why a $15 kitchen scale upgrades every bake. If your recipe uses metric cups (250 ml), the weights run about 5% higher.
