1 calorie = 4.1868J (J=Joules)
That is 0.0041868kJ
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.
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
The conversion is 4.2 Joules per calorie, so 4 kcal is 16.8 kJ.
a joule is smaller 1 kcal = 4.184 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.
The most popular two heat energy units are: Calorie and BTU (British Thermal Unit).Both these units are obsolete. These days, allforms of energy are measured in joules.
The two main units of Energy are the Joule and the Calorie. The Joule is normally represented as the KiloJoule (kJ), which is equivelent to 1000 J. The Calorie is represented as Kcal. 2000 Kcal (calories) is given as the Guideline Daily Allowance for most adults. 1 calorie = 4.184 J or equivalently, 1 kcal = 4.184 kJ Google calculator: http://www.google.com/search?q=1+calorie+in+joules&btnG=Search Wiki Joule entry: http://en.wikipedia.org/wiki/Joule Wiki Calorie entry: http://en.wikipedia.org/wiki/Calorie
