@Layne-Owen Yes, the background map is not customizable and shows meters. Basically, it is only image behind our data.

@karthikeyank Hello, we visualize forecast based on weather models. Models do not show precipitation in seconds.

@Jacko-Jaxon
These scales both for Thunderstorm and for Rain accumulation are correct.

l/km2 means lightning per square kilometre. Could you imagine 1 lighting per square metre? (It’s not litres per square kilometre)

Rain accumulation can be the accumulation of rain over 10 days and 1m (1000mm) is not a non sense ! This is possible in tropical regions as shown here some weeks ago:

1mbar(millibar) = 1hPa

@AndiDuen
In Thunderstorms layer, l/km2 means lightning per square kilometer.
The amount of rain is in mm or in inches, but never mm/m2. Sometime one uses l/m2 (liter per square meter).
10mm=10l/m2

@robbrooks33
what about https://community.windy.com/topic/7233/wind-settings-for-sailors

Hi @gypsyjon , thanks for your message. Have you tried changing the units this way?

@derekvof
Sorry, on iOS it works for me.

Hi @ukfigs , what exactly is your iPhone model and iOS version? Thank you.

The bug is now fixed. Please test it and let us know. 🙂

@rimfalcon
The solution is may be here :

Change the units in the website, on the wind colour scale. Then the modification is automatically applied to the phone app and widget.

8 plus with ios 12.1

The bug is now fixed. Please test it and let us know. 🙂

I have tried to change wind speed units in widget on iOS and it works for me.
I have changed kt for mph.
Change wind speed units on Windy website. First you must be login
Then select the unit you want on wind scale.

The new setting is saved in your Windy cloud. And it will be applied to your iOS.

There are some Windy layers which cannot be changed when using an Android or iOS device. Rain Accumulation is one of them. If you would like the list of layers which cannot be changed, it is available at Overview of units used on Windy. If you aren't interested in looking up items like this (as most users would not want to do also), then make any of those changes using the Windy website using a browser. Changes made using a browser save to the cloud and will then be available when using either an Android or iOS app. If you cannot make a change using a browser, then submit a bug report.
