Calories in 3 mangoes

From a table row to one mango

1. Read the per-100 g row for mango out of the Indian Food Composition Tables 2017 — analysed on Indian samples, so Indian wheat and Indian milk are not swapped for American ones. It gives 70 kcal ਅਤੇ 0.7 g protein per 100 g.
2. Weigh what is actually served. This site enters 1 medium mango at 200 g (edible pulp only). That weight is the number other calorie sites decline to state, and it is where their answers stop being answers.
3. Multiply, linearly, and print the working: 70 × 200 ÷ 100 = 140 kcal per mango. Nothing is rounded up, adjusted or smoothed — two mangoes are exactly twice one.
4. Reconcile the energy against its own macronutrients with Atwater factors on every build. A row more than 15% away from 4P + 4C + 9F (20% above 6 g of fibre) stops the build rather than shipping.

per mango   =  per 100 g  ×  serving grams ÷ 100
Mango              =     70 kcal ×  200 g ÷ 100  =  140 kcal
energy check       =  4P + 4C + 9F  ±15%  (±20% if fibre ≥ 6 g)
