Onions, green, cooked has about 9 calories per USDA reference amount in the cited USDA reference record. Use the portion controls and preparation factors below to interpret the estimate.

What this number means

A portion-aware estimate, not a promise

A USDA reference amount weighing 15 grams has about 9 calories in the cited source record.

The listed household measures span roughly 9–142 calories across the listed portions. That range describes the source portions below; it is not a confidence interval and does not capture every recipe.

Calculated from the smallest and largest usable household measures listed by USDA for this exact FNDDS record; not a confidence interval.

Inside the source record

Source formulation behind this USDA record

USDA links this survey-food entry to 3 source inputs used to calculate the reference nutrition. Publishing those inputs makes the record easier to inspect and helps explain why two similarly named foods can have different values.

How to read this

3 listed components

The largest listed inputs by source weight are Onions, spring or scallions (includes tops and bulb), raw, Oil or table fat, NFS, Salt, table. The order and weights below come from the standardized USDA formulation, so they offer context for this exact database entry.

103.3 g total listed input weight across the formulation.

Use this formulation to choose a closer record—not to reverse-engineer a recipe. If your meal adds, removes, or substantially changes one of these components, another source entry or a photo-based estimate may fit better.

What changes the estimate most?

This is a standardized USDA survey-food profile, not a measurement of every preparation. Actual nutrition can change with portion size, raw versus cooked weight, cooking method, added fat or sauce.

Food estimates can be sensitive to portion weight, preparation, ingredient ratios, and additions that are difficult to judge from appearance alone.

How we estimated this

Traceable back to the source record

This profile uses FoodData Central Survey Foods (FNDDS). It reports the source serving, calculates the 100-gram comparison from the same record, and scales household portions by their listed gram weights.

About the serving label: USDA describes the underlying portion as “Typical reported amount.” We display it as “USDA reference amount” to make clear that it is a database comparison point—not a suggested portion or a claim about what most people should eat.

It does not reconstruct every possible recipe or infer your plate’s weight. Preparation and recipe differences belong in the uncertainty explanation, not hidden decimal places.
