About this calculator
Estimate cooked weight from a fixed expansion factor: white 3.0×, brown 2.7× and basmati 3.2×. Cooked cups use 158 g per cup, servings use 150 g cooked rice, and calories use 3.6 kcal per gram of dry rice. Rice variety and cooking method change yield; check the package and nutrition label for a more specific result.
Worked example
calculated with the default values below
Uncooked rice 200 g · Rice type White rice (×3) Cooked rice 600 g · Cooked rice 3.80 cups · Servings (150 g each) 4.00 · Calories 720 kcal

Frequently asked questions
How are the cooked weight and serving count estimated?
The model uses expansion factors of 3.0 for white, 2.7 for brown and 3.2 for basmati rice, then assumes 158 g per cooked cup and 150 g per serving. Calories use 3.6 kcal per gram of dry rice. Actual yield and nutrition vary by product and preparation.
