The 4·4·9 shorthand adds to 409 kcal and USDA publishes 409 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)
Calories in a typical serving

How rice and wheat cereal bar compares
Among the 44 snacks items on this site, rice and wheat cereal bar ranks 30 of 44 by calorie density, against a category average of 444 kcal per 100 g — so it is about 8% less calorie-dense than typical for its group.
It carries 2.2 g of protein per 100 calories, so it is not a meaningful protein source.
To burn off one bar (90 kcal), a 70 kg adult would walk for roughly 18 minutes — see the walking calculation on our sister site, or pick a different activity. Treat that as a sense of scale rather than a rule: eating and moving are not a simple ledger.
