How can I change my Apple Watch from Farenheit to Celsius ?

Hi

If changing the option to Celsius in the Weather app on your iPhone does not immediately help (including after changing between the options a couple of times), try restarting your Apple Watch: press and hold the side button until you see the Power Off slider; drag it to turn off; then press and hold the side button until you see the Apple logo.

Open weather app on your iPhone. Look at the the bottom-left corner. Here you should see the symbol of the two metrics. Tap the one you wish to use. It should update the Apple Watch weather app too.

i have tried toggling backwards and forwards between F and C in the iphone weather app but my watch stays resolutely on Farenheit. It used to read celsius, this has happened since I replaced my phone and thus reset my Watch but also upgraded to iOS9.0.2 on the same day so could have been that. Any other ideas?

OK I have managed to fix it. Restarting the watch and phone individually did not work - but then I turned off the watch and phone at the same time, then restarted the phone and then the watch, which I guess forced the watch to pull new data from the phone - and that worked!

Thanks - restarted the watch and phone but still no joy.

Glad you got that sorted out. And thanks for posting the fix.

Thanks
