15,000,000 KTemperature · definition
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
Fusion plasma is a state of matter where atomic nuclei and electrons are separated and nuclei can undergo nuclear fusion.
100,000,000 KTemperature
0 K · absolute zero
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 lower than the temperature of fusion plasma.

15,000,000 kelvin
Temperature: 15,000,000 K; definition.
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
Temperature: 100,000,000 K; defined reference.
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.

- Comparing
- Temperature ↔ Temperature
- Relative size
- We compare temperatures using a difference in kelvins, not a ratio.
How to read the visual
The diagram uses the recorded measurements. Details outside the marked spans do not set the scale.
- The temperature of fusion plasma: This is an illustrative comparison value, not a claim that every example is the same.
Compare temperature differences in kelvins; Celsius and Fahrenheit ratios are not meaningful.
