No matter where I draw data into the EFB from (eg simbrief via a flightpln or microsofts planner) i cant get a trip fuel figure to show in the EFB and my fuel gauges always show in kgs. In all cases the data is planned in lbs and my mass default on the EFB is lbs. This is also true when i select the aircraft prior to flight and look to manage the fuel through there. Always in kgs. What am i missing?
Moved to User Support Hub that is more appropriate for community support.
I have solved this. The system default units dictate for the built in MSFS2024 aircraft. These are in main settings under “language” (obviously! 
). The 3rd party aircraft like Fenix can change units within the EFB but the default aircraft are derermined by the user default.
