I've looked back at a lot of discussion about how TomTom Multi-Sport calculates calories burned. My TomTom reports results in KCal which I believe is incorrect. METs (metabolic equivalent of tasks) multiplied by your weight (in Kg) multiplied by exercise time is how the TomTom computes calories. Here is a way to enter your data without doing the calculation yourself to check calories by this method: (http://ergo.human.cornell.edu/MetsCaloriesCalculator/MetsCaloriesCalculator.htm
). The results are in Cal NOT KCal.
