Celsius and Fahrenheit have shifted zero points. Differences are useful; “twice as hot” in °C or °F is not a physical temperature ratio.

Celsius and Fahrenheit zero points are offsets. Compare temperature differences, not ratios in °C or °F. The kelvin axis starts at absolute zero.
A little perspective
15,000,000 kelvin is 85,000,000 K cooler than Fusion plasma.

15,000,000 kelvin
Celsius and Fahrenheit have shifted zero points. Differences are useful; “twice as hot” in °C or °F is not a physical temperature ratio.
Fusion plasma
A 100 million K plasma example. High temperature alone does not specify total thermal energy.
Defined examples — our methodology
The marked temperature is calibrated. Unmeasured illustration details are representative.
Measurement details
Why these numbers?
The visual compares temperature with temperature. The records below preserve each value’s basis and caveats.

- Comparing
- Temperature ↔ Temperature
- Relative size
- Temperature comparisons use an absolute difference in kelvins rather than a multiplicative ratio.
How to read the visual
The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.
- Fusion plasma is labelled defined reference; treat the displayed value as a comparison anchor rather than false precision.
