You should be able to choose metric or imperial in settingsOn the go app, the Rth is in meters? I set it to feet but rth seems to be listed in meters.
Well live and learnWithout looking, I'm pretty sure a few of the menu choices are in meters only even if you have selected Imperial. (Maximum altitude for instance).
I just set mine to metric when I got it and never thought about it againYou get used to it after a while. They've been in metric ever since the first version of DJI GO was released.
Must be confusing for you guys that work in imperial!
