Brown rice:
grams to cups.
Uncooked brown rice weighs 190 g per cup — about 3% more than white rice (185 g) because the intact bran and germ layers add density to each grain. The bran also makes brown rice cook more slowly and absorb more water.

Bran retention and its effect on grain density
Brown rice retains the bran and germ that are removed during white rice milling. These outer layers are denser than the starchy endosperm that dominates white rice — so each brown rice grain is slightly heavier per volume than a white rice grain. The result is a small but consistent 5 g difference per cup: 190 g for brown versus 185 g for white. When a recipe calls for "rice" without specifying type, most American recipes assume white rice. Substituting brown rice by cup volume will add slightly more mass and dramatically change the cooking time (brown rice typically needs 45–50 minutes versus 18–20 minutes for white).
Measuring brown rice for baked goods and salads
Brown rice appears in baked goods (brown rice flour is made from it), grain salads, and stuffings. In these applications, measuring dry brown rice by grams rather than cups ensures you're adding the correct quantity before cooking. For grain salads where you want a specific final volume of cooked rice, remember that brown rice expands to about 2.5× its dry volume during cooking (slightly less than white rice's 3×), so 190 g (1 cup) of dry brown rice yields about 2.5 cups of cooked rice.
