Do parboiled rice and uncooked rice weigh the same in ounces?

No, parboiled rice and uncooked rice do not weigh the same in ounces. Parboiled rice has been partially cooked and often contains some moisture, which can slightly increase its weight compared to uncooked rice. Additionally, when cooked, rice absorbs water and expands, further affecting its weight. Therefore, their weights differ depending on their preparation state.
