If you don't see menu at left, CLICK
then CLICK 'Energy' button.
you are converting Joules to Food Calories, please
Notice there is a popup menu entry for calories
(food), kilocalories (th), and kilocalories (IT).
They are all about the same: 1 Joule(s) = 0.000239
kilocalorie. A food calorie is the same as a
kilocalorie (th), but a food calorie is not the
same as a calorie (in science). Your best choice is
to convert calorie (food) to Joules. DON'T use any
of the other calories in the menu because 1000
calories = 1 kilocalorie.
