Sorry these arguments about the superiority or otherwise of a unit of measurement are just silly.
It is 100% related to what you grew up with and are familiar with.
No one who grew up with Celsius has any issue discussing weather or adjusting thermostats and the only people who struggle would be people who didnt grow up with it.
Does it actually taste nice though? I like really hot food, e.g. love the taste of buldak bokkeum myun and regularly eat the Samyang 2x. But I find these chilli's have some really unpleasant flavour compared to more 'normal' chillies.
