1 calorie = 4.1868J (J=Joules)
That is 0.0041868kJ
"KJ" is a short form for "kilojoule". It is the Metric system alternative to the British system "calorie". Both measure the amount of energy in a food, available to a human who eats it.
1 kJ = 239.006 cal = 0.239 kcal
calories x 4.1868 = kJ
About 1/4 of a calorie per kJ
1 food calorie (Cal) = 4.184 kilojoules (kJ)
Approximately 2080 calories. one calorie = 4.184 KJ of energy
10450 Kj Per day for Man. 1 Calorie is equal to 4.18 Kj
Units to measure energy. Usually written kilojoule or kJ.
calorie was but is now obsolete. Joule and kJ are used instead because they are the SI energy unit
1 Joule = 0.2390 cal (calorie) or 4.18 J=1 cal
4.184 Kilojoules make up 1 calorie. If you have any food product that contains for example around 400 Kj it will then obviously be the equivalent to about 95 calories. 50 calories will be the equivalent to around 210 Kj
Remember that one calorie is equivalent to 4.18400 Joules. Also remember that a food calorie (Calorie) is equal to 1000 calories. So one Calorie is equal to 4.184 kJ of energy.
The conversion is 4.2 Joules per calorie, so 4 kcal is 16.8 kJ.
The calorie is based on metric mesurements and is therefore the same anywhere in the world. However use of calories is discouraged and instead kJ should be used. kJ are easier to calculate.
a joule is smaller 1 kcal = 4.184 kj
