Distance values - miles or km?

[IanHayes]

Using the Web API,   various calls will include a 'distance' attribute value.

However,  I can't find a way of determining the unit of distance,   whether the value represents miles or kilometres.

Any suggestions?

Hi @IanHayes,

The distance traveled for the day displayed in the activity is defined by the Accept-Language header. You can also use the Get Profile endpoint to see what unit preference the Fitbit user selected by locating the distanceUnit element in the response.

I hope this helps. Let me know if you have any other questions.
