The 4·4·9 shorthand adds to 446 kcal and USDA publishes 446 kcal. The arithmetic closes, so the axis above is simply that figure divided by the shares.

How this is worked out
- USDA measures every nutrient per 100 g of edible portion. That row is published here unchanged — nothing is rounded up, smoothed or "adjusted".
- The energy figure is USDA's own, derived with food-specific factors. This site never computes the calorie count it publishes.
- 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.
- A serving is a straight proportional conversion of the per-100 g row, using USDA's own household measures for the grams.
- 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)
