I grew up in a metric system country, and moved to the US. Miles are not a problem, I'm driving 60mph, I see that I have to drive 120 miles it will take me 2 hours. A pound is roughly a half kilo. A pint is about half a liter. But what drives me mad is Fahrenheits after 15 years in the US I still struggle with it.

It sounds like you have a similar process to me - you don’t actually “think” in or understand the imperial units - you have just memorised benchmark amounts and conversion metrics. That’s why you can’t get your head around fahrenheit - the conversion isn’t an easy one to mentally apply every time.
