Dry to cooked rice weight calculator
Convert dry rice to cooked weight or cooked rice to dry weight. Use a measured batch to divide meal-prep portions.
Free. No account required.
How the calculation works
Estimated cooked weight = dry weight × cooking yield ÷ 100. Reverse it by dividing cooked weight by the yield fraction. The preparation preset supplies a starting estimate that you can edit.
My batch uses your measured weights: dry equivalent = cooked portion × dry batch ÷ cooked batch. Use the same edible food for all three weights.
Rice absorbs water, so cooked weight is greater than dry weight. The preset is an estimate from Indica varieties, not a universal factor for brown rice, instant rice, or every cooking method. Measure your own drained or absorbed-water batch when possible.
A worked example
At a 301% yield, 100 g of dry rice becomes about 301 g cooked. If your own 200 g dry batch weighs 560 g cooked, a 140 g portion corresponds to 50 g dry.

Common questions
Can I use this for brown or instant rice?
Use My batch. The starting estimate comes from Indica rice research and does not establish the yield of brown or instant rice.
Is the rice package nutrition for dry weight?
Check the label for dry, uncooked, cooked, or prepared wording. Match your logging weight to that basis. Added butter, oil, and sauces need their own entries.
Can I convert cups?
This tool converts weight. A cup of dry rice and a cup of cooked rice have different densities. Use grams, ounces, or pounds from a scale.
