Estimates. Portion weights are the published averages for this food. A cup of chopped carrot and a cup of sliced carrot do not weigh the same, so treat the result as approximate.

About zeros. A value of 0 may mean the nutrient is genuinely absent, or that it was not measured / was below the limit of detection. USDA does not distinguish between the two, so this site does not use 0 values for filtering or for "free from" claims.

This converter does not use zero values to claim a food is free of anything, and it is not dietary or medical advice.

Why there is only one energy value here

USDA publishes three different energy nutrients (IDs 1008, 2047, 2048) plus a kilojoule value. This page uses 1008 — Energy — falling back to the others only when it is absent. Sites that mix them can report different calorie counts for the same food.

Published portion sizes

These are the measured weights this site uses for conversion.

PortionGramsEnergy
1 (cup pieces or slices)7015
1 (cup whole)9621
1 (large)235
1 (slice)61
1 (medium)184
1 (small)102

Portions without a measured weight are listed but cannot be converted — we do not guess a weight for them.

Allergens: do not rely on this page

This dataset has no structured allergen field, and reference values describe a generic food — not the product you are holding. Always read the actual label before eating anything.

If you have a food allergy, treat this page as background information only.
