4.22 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.

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
4.22 kelvin and Boiling helium are at the same temperature.

4.22 kelvin

Boiling helium
Approximate normal boiling point of helium at one atmosphere.

Why these numbers?
The visual compares temperature with temperature. The records below preserve each value’s basis and caveats.
Boiling helium
4.22 KTemperature · approximate
Approximate normal boiling point of helium at one atmosphere.
- 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.
- Boiling helium is labelled approximate; treat the displayed value as a comparison anchor rather than false precision.
