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
100 degrees Celsius and Boiling water are at the same temperature.

100 degrees Celsius
Celsius and Fahrenheit have shifted zero points. Differences are useful; “twice as hot” in °C or °F is not a physical temperature ratio.
Boiling water
Fresh water at approximately one standard atmosphere. Altitude and pressure change the boiling point.
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.
Boiling water

Fresh water at approximately one standard atmosphere. Altitude and pressure change the boiling point.
- 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 water is labelled defined reference; treat the displayed value as a comparison anchor rather than false precision.
