The 4·4·9 shorthand adds to 527 kcal; USDA publishes 544 kcal−17 kcal, 3.1% apart. That gap is expected, not an error: USDA derives energy with food-specific factors and, for many items, discounts the fibre that the shorthand still counts at four. The published figure is the better one, so the axis above is scaled to it and the shares are what the shorthand is genuinely good at.

How this is worked out

  1. USDA measures every nutrient per 100 g of edible portion. That row is published here unchanged — nothing is rounded up, smoothed or "adjusted".
  2. The energy figure is USDA's own, derived with food-specific factors. This site never computes the calorie count it publishes.
  3. The Atwater shorthand 4 · 4 · 9 is applied to the protein, carbohydrate and fat grams only to split that energy into shares — and where the shorthand disagrees with the published figure, the gap is printed rather than hidden.
  4. A serving is a straight proportional conversion of the per-100 g row, using USDA's own household measures for the grams.
  5. The walking figure uses MET 4.0 at 70 kg, the same equation the sister site publishes.
per serving   = per 100 g × serving grams ÷ 100
energy shares = 4·P + 4·C + 9·F      (P, C, F in grams)
walk minutes  = kcal ÷ (4.0 × 3.5 × 70 ÷ 200)
