I'm very similar. I have even lived in Europe a couple of times. But I don't even try to think in Celsius anymore, I just don't see a benefit and my brain rejects it. 90% of the time when I'm boiling water it's high up on a mountain and it boils below 100C in elevation. Also who cares if the water is 95C or 200F, it's not as hot as I'd like it to be.
