m/s for wind speed in weather card

[WallyDW]

m/s is the official standard for measuring wind speed (https://en.wikipedia.org/wiki/Wind_speed), but the weather card seems to assume its km/h.
Many weather forecast publish in m/s, so its just the suffix that is missing in the viewing.
A few publish in other standards and for those there might be some calculation required in the conversion.
One solution is to build it all into the weather card.
Another is to split the sensors up, so users can make a template for that sensor alone.
