i've heard it argued that Fahrenheit is the more human temperature scale, and weather is used as the example, with 70°F as a comfy air temperature and 100°C being very hot.
i'd like to argue that Celsius is the more human one because it's perfect for cooking. 100°C to boil soup. 70°C is nice and hot for eating. 50°C and below is getting a little lukewarm. <10°C to keep in the fridge. under 0°C to freeze it.
