The kitchen scale has smart buttons that already know the general calorie content of certain foods.

So, when you weigh something, you can press the button that corresponds to the food you’re weighing. The scale will then give you an estimate of how many calories there are per gram in that food.

For example, if you weigh flour, the scale already knows the calories for wheat flour, so it can give you an idea of how many calories are in what you’re weighing.
