When different macronutrients (e.g., carbohydrates) are metabolized, they yield different amounts of energy, commonly measured in kilocalories.
They are given by the following conversion factors:
carbohydrates = 4 kcal/g
protein = 4 kcal/g
fat = 9 kcal/g
If the slice of pizza contains 29 g carbohydrates, that means there are 4 kcal/g × 29 g = 116 kcal from carbohydrates. It contains 13 g protein, so there are 4 kcal/g <span>× 13 g = 52 kcal from protein.
The total number of kilocalories is 280, of which we have accounted for 168 (116+52). 280–168=112 kcal.
So, there are 112 kcal from fat. Using our conversion factor, 112 kcal </span><span>× 1 g/9 kcal = 12 g fat.</span>
To convert 390 ml to grams, besides the volume we have to know the substance’s density ρ in g/cm3<span> or in any other unit. Alternatively, when we know the material, then we can look for its density in a search engine. As explained on our home page, 390 ml equal 390 cm</span>3<span>, and as also outlined there, in common use the equation for water is 390 milliliter = 390 g</span>
