How do you calculate the calories burned?

The amount of calories you burn depends on your body weight, size, age, sex and - most importantly - the distance you cover. The same amount of steps might result in different calorie values depending on your activity. Why? Your step length is usually longer when running than when you are simply strolling around in the city. This way you cover a much greater distance with the same number of steps – which in return results in a much higher calories-burned value.
