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
10,000 kelvin is 4,228 K higher than the surface temperature of the Sun.

10,000 kelvin
Temperature: 10,000 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.
Sun
Surface temperature: 5,772 K; approximate.
Our star, modelled with the IAU nominal solar radius. “Surface” means the visible photosphere. The core is much hotter; this is not a solid surface.
IAU — nominal solar and planetary conversion constants
The marked surface temperature is calibrated. Unmeasured illustration details are representative.

- Comparing
- Temperature ↔ Surface 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 surface temperature of the Sun: This is an estimate; check the notes for its rounding and uncertainty.
Compare temperature differences in kelvins; Celsius and Fahrenheit ratios are not meaningful.
