If you're having folks over for dinner and serving rice this calculator will help you figure out how much rice you'll need to prepare, both cooked and uncooked amounts. The calculator will help you with figuring out the number of servings for 10, 20, 50 or more people. It will also give you ratios depending on whether you want regular rice or sticky rice. For reference, the average serving size of cooked rice as part of a main dish is one cup cooked and 1/2 cup cooked if used as a side dish.
The amount of water to use for uncooked rice is largely dependent on the type of rice you are using and your cooking method. This calculator is based on using white long grain rice cooked over a stovetop. The standard water to rice ratio is 3:1. That results in 3 cups of cooked rice using 1 cup of uncooked rice to three cups water.
