I’m in the US but prefer metric. So I use Celsius on my phone, laptop etc. For my own use there’s a little mnemonic that makes it unnecessary to convert and helps build intuition. It goes “30 is hot, 20 is nice, 10 is cold, 0 is ice.” That pretty much hits all the practical needs I have for my weather forecasts etc.
If I need to convert though I do the multiply by 2 and add 32 formula for a rough estimate

Multiply by 2 and add 30 is a bit more accurate for weather temps, since 9/5 is less than 2.
