The amount of cooked rice you get from 1.5 cups of dry rice depends on the type of rice you are using and the cooking method. Generally, 1 cup of dry rice will yield about 3 cups of cooked rice.
Assuming you are using long-grain white rice, which is a common type, 1.5 cups of dry rice will typically yield approximately 4.5 cups of cooked rice. This is based on the standard rice-to-water ratio of 1 cup of rice to 2 cups of water. As the rice absorbs the water during cooking, it increases in volume.
Keep in mind that other types of rice (e.g., short-grain, medium-grain, brown rice, wild rice) might have different cooking times and absorption rates, which can slightly affect the final yield of cooked rice. Always follow the specific cooking instructions for the type of rice you are using to achieve the best results.
