Change MP/H to KM/S

Get Help
1

Hello,
I would like to implement the weather forecast.
It seems to work, but the wind speed is in MP/H, and I want it to be changed in KM/H and if possible convert it to wind force.

Can anybody help me with this?

Regards, Peter

Hello,

problem 1 solved by choosing Canada for Units. Now I have KM/H.
But I also would like to show the windspeed, in force. For example windspeed of 6-10 km/h is wind force 2, and wind speed 20 - 28 km/h is windforce 4. Etc.

Any idea how to get started with this issue?

We can only show the data that Darksky give us, which I believe is MPH/KPH.

If the force value is in the data returned, then you could edit the widget template and select that value in preference to the MPH/KPH.

Hi,
No, Darksky don’t returned the value of windforce.

I have Peter programmed a Javascript to do the job.

Hi Alex,

As forummember SteitzTo also mentioned: via a javascript it is possible to convert the windspeed to windforce.
It is working perfect.
