@r31ya I just Googled for a few seconds and this is the top result:
"The metric unit of temperature is the degree Celsius (C), which replaces the English system's degree Fahrenheit (F). In the scientists' SI, the fundamental unit of temperature is actually the kelvin (K)."
@r31ya should look stuff up before making bold claims
celcius and kelvin in particular definitely are related to metric, although to my surprise fahrenheit is apparently not tied to the imperial system, its just commonly used in conjunction with it in america
I feel like this chapter is simply Ichi just trying to say ''Use your head for once dimwit, its for your own sake'' to Caph but with fancy water magic through the whole night
