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.

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.
