0 F is defined as the lowest temperature a guy was able to reach with some random mixture which is arbitrary.
But 0 C is commonly defined as the point at which water turns from solid to liquid and the other way round. Scientifically it’s ever so slightly off but still it’s defined via Kelvin.
Celsius is defined at the arbitrary standard pressure, different pressure values change how water acts (this is very noticeable at 100C - boiling). Kelvin steps are defined from Celsius. Even the speed of light which is constant is still defined in terms of an arbitrary time unit.
Seconds are clearly defined by one specific caesium-133 transition
The second […] is defined by taking the fixed numerical value of the caesium frequency, ΔνCs, the unperturbed ground-statehyperfine transition frequency of the caesium 133 atom, to be 9192631770 when expressed in the unit Hz, which is equal to s−1
Usually you’d measure it relative to room temperature. Probably harder in this scenario (I don’t have a thermometer laying around, but 20°C is probably a good starting point.

Kinda misleading lower limit on the graph
TBF 0C and 0F are kinda arbitrary values.

@30p87 @bluGill @WolfLink @einkorn Wow wow guys… that’s just RRDTool doing its thing with graphs 😆

Esp. for CPU temps. A much more interesting range is 50-100C.
