If you have 5.5 oz of uncooked rice how would that measure in cups?

5/6 cup of white rice.

Regular white rice triples in volume when cooked. (5 x 1/2 cups) x 1/ 3 = 5/6 cups

Minute rice expands much less. Nine units of minute rice yield 16 units of cooked rice. (5 x 1/2 cup) x 9/16 = 45/32 cups ~ 1 1/2 cups
