Go to Fitbit.com dashboard and click on the gear icon at the upper right and then on settings. Scroll down to Units and click on the down arrow and change length to Centimeters. Scroll on down and click on submit and then sync your tracker. This selects metric and now your temps should be in Celcius.
Best AnswerThank you very much for your reply. This then causes me a problem as I’d rather have my distance in miles!!!
Best AnswerUnfortunately there isn't currently any way to set the distance and temperature independently. It might be worth adding your vote to this feature suggestion, the more votes it gets, the more chance it has of being implemented.
