One US cup of dry long-grain white rice weighs 198 g (7 oz) on King Arthur Baking's ingredient weight chart, which lists 1/2 cup at 99 g. USDA's FoodData Central puts a cup of raw long-grain white rice at 185 g. Neither source says how the cup was filled, so treat a cup of dry rice as 185 to 198 g and use a scale when a recipe gives grams.
Cooked rice is a different number. USDA lists 1 cup of cooked long-grain white rice at 158 g, about 5.6 oz by weight, with about 205 calories. Medium-grain white rice comes in at 186 g per cooked cup and brown long-grain at 202 g.
The cup packed with a rice cooker is smaller than a US measuring cup. Panasonic's support pages give its measuring cup as about 180 mL, which is 0.76 US cup, close to 3/4 cup. If your cooker's instructions count rice in its own cups, measure with that cup, or with 3/4 US cup per rice-cooker cup. For other ingredients see grams in a cup.

Calories in a cup of rice
USDA lists cooked long-grain white rice at 130 kcal per 100 g, so by its 158 g cup:
- 1 cup cooked: about 205 calories.
- 1/2 cup cooked (79 g): about 103 calories.
- 3 cups cooked: about 616 calories.
Dry rice is listed at 365 kcal per 100 g: 1 cup uncooked (185 g) has about 675 calories, 1/2 cup about 338 and 1/4 cup about 169. A cooked cup of medium-grain white rice has about 242 calories and brown long-grain about 248.
How much cooked rice does 1 cup of dry rice make?
A little over 3 cups. Cooking adds water and no calories, so the 675 calories in 1 cup of dry long-grain white rice end up spread over about 3.3 cups of cooked rice at 205 calories each (both figures from USDA). By the same math, 1/2 cup dry makes about 1.6 cups cooked and 1/3 cup dry about 1.1 cups. The yield in your pot depends on the rice and how much water it takes up.
