How to use

  1. Choose a food preset.
  2. Adjust raw grams and cooking ratio if needed.
  3. Cooked weight and nutrition per cooked 100 g appear on the right.

Useful tips

  • Useful when you want to estimate nutrition for cooked rice after cooking; adjust inputs to compare outcomes.
  • Prefer product labels, recipe notes, and equipment markings when available.
  • When unsure, start with a smaller or shorter estimate and adjust from the actual result.

Formula

Cooked weight = raw weight × cooking ratio. Total nutrition = nutrition per raw 100 g × raw weight ÷ 100.

Notes

  • Water content, oil absorption, cooking method, and product differences can change cooked weight significantly.
  • Rice and pasta ratios are rough presets. Adjust the ratio if you have measured values.
  • Use this as a cooking estimate, not as dietary guidance.
