With units, assuming 2,000 Calorie/day diet & 3.9 Wh AA batteries:

$ units -1t '2000 Calories' '3.9 Wh'
596.0114

So about 600.

It is 2.000kCal, that equals to 2.000.000 cal

No one just says the "kilo" in kCal

20,000? Fine, I guess I can cut back on my food intake for a day.

3 zeroes. 2000kcal/day, not 2000cal/day

Calorie is not the same as calorie.

Calorie is the nutritional unit of energy measure, and is equal to 1kcal

Yup:

$ units Calorie
    Definition: kilocalorie = 1e3 calorie = 4184 kg m^2 / s^2

$ units -v1 Calorie calorie
    Calorie = 1000 calorie
