But your second sentence is entirely the point. Practically if you’re used to C then you know exactly what the habitable human range is, and Fahrenheit is meaningless to you (I literally have no intuition for it - I know that 32 is zero C and and 100 is around 40 C, so I know what that feels like, but I can’t imagine at all what any Fahrenheit temperature between that feels like without googling the conversion). So 0-100 being ‘human scale’ is nothing but perhaps a bit of a fun novelty, the only thing that is important is either having or building the familiarity and intuition (which is mostly just from experience of everyday use).
