If you are converting Joules to Food Calories, please note:

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.
