joules or kacl

Asked by  | 15th Feb, 2014, 07:11: PM

Expert Answer:

Though 'joules' is the SI unit of energy, calorie and kilocalorie are also the units of energy.
 
Now, 1 kilocalorie = 1000 calories = 4180 J
 
Hence, the nutritional value of different constituents of food items can be written in kcal.
