It would be nice to have the option of speed in miles per hour, and elevation in metres.
This is probably the most common units in the UK.
Good point.
I'll put that on the list. We should be able to make this happen around the VIRB Edit 2.2 / 2.3 time-frame.
We'll add that as well eventually. Thanks for your feedback!
2.2 will have an option for nautical distance measurements (and separate meter/feet selection for distance/speed vs. Elevation).
