OK, thanks. I believe in our observations over the last couple years, the predicted Gusts seem too high compared to our other sources of weather station info, as well as the media reports. We normally leave the default on 'ECMWF' in Windy, but now we will try to use 'GFS' (or 'NAM') and see if we are running in "more parallel" between our info and Windy, specifically for predicted Gusts. Again, thanks for the help and good work on this. As an electric utility company, we depend on great information to help us with storms, power outages, etc...so you see that the wind speed, gusts, etc is crucial data to us.

As I see, there is no answer yet. Though I'm an iPhone owner, but I hope I can help you.
There is no option for this on iPhone as I know, maybe nor on android.. You can change it only on the online https://www.windy.com/?visibility,46.920,21.533,4 website (at visibility) by clicking to the unit in used, so it will switch to another units, you can choose that you want by your discretion.
Anyway you can determine it by calculator with the following formulas:

1 KM = 0,54 NM (nautical miles)
1 KM = 0,62 SM (statue mile)

1 NM = 1,852 KM
1 SM = 1,61 KM

Or direct change it simple with a converter application, such as "Vert" or "Amount Plus", these are the best converters as my experience.

You have 3 options with the units of visibility on the website:

km sm flight rules (LIFR, IFR, MVFR, VFR - in aviation)
