Measuring cup vs. rice cooker cup
The cup that comes with a rice cooker is not a US measuring cup. Most rice cooker cups hold about 180 mL, compared with about 237 mL for a US cup, so a rice cooker "cup" of long-grain rice weighs roughly 150 g.
Always use the cup that matches your instructions: the water lines inside a rice cooker are designed for the rice cooker's own cup.
Tips for measuring uncooked long-grain white rice
- Rice varieties differ in grain size and shape, so a cup of short-grain, jasmine or basmati rice won't weigh exactly the same as long-grain. For recipes given in grams, such as risotto or sushi rice, weigh instead of converting.
- Weigh rice dry, before rinsing. Wet rice holds water and weighs more.
- Cooked rice is much lighter per cup than dry rice: King Arthur Baking's chart lists cooked brown rice at about 170 g per cup.

Sources and method
The cup weight on this page comes from King Arthur Baking's Ingredient Weight Chart, which lists uncooked long-grain white rice as 1/2 cup (long grain, dry) = 3 1/2 oz = 99 g. All other figures are calculated from that weight using a US customary cup (236.6 mL), 16 tablespoons per cup and 3 teaspoons per tablespoon. Using a 250 mL metric cup? Multiply the grams by about 1.06. Brand, humidity and measuring technique can shift real-world weights by a few percent, so weigh when precision matters.
