15 It depends on the amount of calories of the apple. What size is the apple?
100 grams are in 1 hectogram.
There are 1,000 grams in a kilogram
1120 grams 1 kilogram = 1000 grams 1 gram = 0.001 kilograms
1 milligrams (not milliagrams!) = 0.001 grams or 1/1000 g.
825 kcal
1 kCal = 1000 Cal or I Cal = 1/1000 kCal
There are 171.04 kcal in 100 grams of boiled chicken.
1 kcal = 1000 cal. 1 cal = 4.18 J
9g of Agave Nectar provides 25.7 kcal
760 kcal/ton clinker
The difference between kcal and cal is 1000 cal = 1 kcal. However, we usually count food calories with kcal, and use kcal and cal interchangeably. Therefore, 9 kcal [Food Calories] = 9 cal. So, to the point: If there are 9 kcal in 1 g of fat, there are 9000 kcal in 1 kg of fat (1 kg = 1000 g).
1000 calories in one kcal so 1000 is to 1 as x is to 60 = .06 kcal
1 gram protein = 4 calories 4 gram protein = 4x4= 16 calories
1950 grams
50 Kcal. Each gram of protein = 1 Kcal Each gram of fat = 9 Kcal Therefore 5g of Protein = 5Kcal 5g of Fat = 45kcal 5Kcal + 45kcal = 50Kcal
Assuming 4 kcal/g for carb and protein and 9 kcal/g for fats, the total would be (15 x 9) + (25 x 4) + (20 x 4) = 315 kcal.
