Food weight and portion guide
Meygoo polo (shrimp rice): calories and portions
Worked recipe estimate using listed ingredients and an assumed finished weight
The shrimp in this example is cleaned and cooked; shells are excluded.
This estimate uses the ingredients below and an assumed finished recipe weight of 1,700 g. It is a calculation, not a measurement of your meal. See ingredients and quantities.
Calculate your portion
Enter 0.1–5,000 g. Exclude inedible skin, stones and bones.
Does your finished recipe have a different weight?
Adjust the finished weight only when the ingredients and quantities below are identical and the difference comes from water. This setting does not account for added or removed meat, oil or other ingredients.
Enter 0.1–50,000 g. Default: 1,700 grams.

Nutrition by weight
| Weight | Calories | Protein | Carbohydrate | Fat |
|---|---|---|---|---|
| 100 g | 136.1 | 7.6 g | 18.3 g | 3.5 g |
| 300 g | 408.4 | 22.8 g | 55 g | 10.6 g |
| 600 g | 816.8 | 45.6 g | 110 g | 21.1 g |
Values are scaled from the per-100-g data and rounded. “Calories” means kilocalories (kcal).
Ingredients behind this estimate
The table lists the ingredients used in this worked calculation. Raw and cooked weights are not interchangeable. Assumed finished recipe weight: 1,700 g.
| Ingredient and preparation state | Weight | Calories in the batch |
|---|---|---|
| Rice, white, long-grain, regular, enriched, cooked [1] | 1,000 g | 1,300 |
| Crustaceans, shrimp, cooked [2] | 400 g | 396 |
| Onions, raw [3] | 150 g | 60 |
| Tomato products, canned, paste, without salt added (Includes foods for USDA's Food Distribution Program) [4] | 60 g | 49.2 |
| Coriander (cilantro) leaves, raw [5] | 100 g | 23 |
| Oil, canola [6] | 55 g | 486.2 |
It is assumed that the mentioned ingredients and oil remain in the food. Absorbed or evaporated water is included in the final weight. Spices, salt and minor additives not mentioned are not calculated. If your composition is different, count the actual ingredients separately.
Tips for weighing and logging
Oil used for both the shrimp and rice belongs in the total recipe oil.
To calculate manually, multiply your portion weight in grams by 136.1 and divide by 100. For example, 300 g provides approximately 408.4 kcal, assuming the same composition and final weight.
When logging a photo, check the food, cooking method and estimated portion before saving. A photograph cannot reliably show hidden oil or exact weight.
Sources and calculation method
We total the energy and macronutrients of the listed ingredients, divide by the assumed finished recipe weight and multiply by 100.Library method and limitations
