Dan565 I had exactly the same question. I live in Scotland where its degrees Celsius (commonly minus degrees Celsius it was -18 a few days ago) but we use miles per hour (or knots) for things like wind speed. Although the default Samsung Weather Channel App has an all or nothing approach with regards to metric or imperial, Google Play (and the Galaxy Store) do offer upgrades to version 10.27 which does provide degrees Celsius AND miles per hour wind speed. The only problem is that these apps don't upgrade the original Weather Channel App but sit along side it. If you tap the weather widget and weather radar its only the original app that'll open.
