IMO there is no direct conversion. It depends what your Max heart rate, and average heart rate was on the run. Because i am on Xenadrene RFA, i track my heart rate during my cardio so i know exactly where i am at different times. So to really move over you need to know this info so that you can match heart rates from machine to machine.
