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

Water triple point
The water triple point is the unique temperature and pressure at which water can exist simultaneously as solid, liquid, and vapour in equilibrium.
0.01 °CTriple-point temperature
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
10 degrees Celsius is 9.99 K higher than the water triple point.

10 degrees Celsius
Temperature: 10 °C; definition.
Celsius and Fahrenheit have shifted zero points. Differences are useful; “twice as hot” in °C or °F is not a physical temperature ratio.
Water triple point
Triple-point temperature: 0.01 °C; specified.
The triple point of water is 273.16 K for a specified isotopic composition at its equilibrium pressure. It is distinct from ordinary freezing water at atmospheric pressure.

- Comparing
- Temperature ↔ Triple-point 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.
Compare temperature differences in kelvins; Celsius and Fahrenheit ratios are not meaningful.
