One gram of protein contains about 4 kilojoules (kJ) of energy.
There are approximately 17 kilojoules (kJ) in 1 gram of protein.
There are 9 kilojoules (kJ) in 1 gram of fat.
Fats provide approximately 9 calories (37.7 kJ) of energy per gram.
The specific heat of kerosene is 2,01 kJ/kg.K.
To convert kilojoules (kJ) to kilocalories, you can use the conversion factor of 1 kJ is equivalent to 0.239 kcal. So, 240 kJ is equal to 240 x 0.239 ≈ 57.4 kilocalories of heat.
There are approximately 17 kilojoules (kJ) in 1 gram of protein.
There are 9 kilojoules (kJ) in 1 gram of fat.
1 gram fat produce 9 calories i.e. 37.7 kJ
There's 375 calories in 100 g of dextrose (that's 1575 KJ's).
I've been looking everywhere for home work and finally got the answer: 2206 kJ. :)
To convert grams (g) of a food product to kilojoules (KJ), you need to know the specific energy content of the food. Different macronutrients (carbohydrates, protein, fats) provide different amounts of energy per gram. You would need the breakdown of these nutrients in the food product to accurately convert grams to kilojoules.
proteins are not classified as viable energy as they are comprised of many many amino acids which makes them impractical to go to all the effort to break down, instead carbon chains like glucose, surcose are better forms of energy, same may be said for a few fatty acids
About 4 kilocalories per gram or 4 Calories/g or 17 kJ/g. Calories are confusing because of stupid standard with uppercase C, prefer kJ !
Fats provide approximately 9 calories (37.7 kJ) of energy per gram.
1 gram carrys 9.45 calories/38 kJ
The amount of calories that 20 protein bars contain varies and depends on the type of protein bar one consumes. One Special K protein bar in a chocolate peanut butter flavor contains roughly 180 calories, so having 20 of them would be 3,600 calories. This number is roughly twice the average daily calorie intake for men.
They contain 4 clalories per gram of carbohydrate :)
