Show the Local Weather: SI or Imperial

I’m almost done with the project, but I have a question about the json file I get. In which measurement scale is it: SI or Imperial? For example, wind speed, is it in km/h (kilometers per hour) or mph (miles per hour)?

This one. https://fcc-weather-api.glitch.me/

I’m not sure either. I just wanted to add the wind speed as well, but if we don’t know for sure, I’ll have to forget about it. Thanks anyway. :slight_smile:
