How this works

USDA dietary guidance defines a standard serving of a cooked grain like rice or pasta as 1/2 cup. This calculator uses that figure to convert between a total cooked volume and a number of standard servings in either direction.

Source: Based on the USDA MyPlate standard serving size of 1/2 cup cooked grains, rice, or pasta per serving.

Frequently asked questions

What is a standard serving size of cooked rice?

USDA dietary guidance uses 1/2 cup of cooked rice, pasta, or other grain as one standard serving.

How much raw rice do I need to get 4 cups cooked?

This calculator works from cooked volume; raw rice roughly triples in volume when cooked, so about 1.33 cups of raw rice yields roughly 4 cups cooked — check your specific rice variety's package instructions for the exact ratio.

Is 1/2 cup a realistic serving for a hungry adult?

It's the standard dietary-guidance serving size, but many people eat more as a main-dish portion — treat it as a planning baseline and scale up for heartier appetites.
