Serving and food-state notes

The baseline is exactly 100g before cooking, with edible flesh and skin. A kitchen scale is the most reliable way to match it.

USDA also lists a small raw potato at about 170g, a medium at about 213g, and a large at about 369g for this record. Potato variety and preparation change the result.

How this answer was calculated

For foods without sugar alcohols, this site uses net carbs = total carbohydrate − dietary fiber. “Net carbs” is a tracking convention, not a separate nutrient on the standard U.S. Nutrition Facts label.

The serving is the same 100g basis as the source. Therefore 17.5g total carbohydrate − 2.1g fiber = 15.4g net carbs.
