Planck temperature
The Planck temperature is a theoretical temperature scale at which quantum gravitational effects are expected to become important.
1.417 × 10³² 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.

1.416784 × 10³² kelvin
Temperature: 1.417 × 10³² 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.
Planck temperature
Temperature: 1.417 × 10³² K; theoretical.
A theoretical temperature scale where quantum gravity is expected to matter. Current physics does not establish it as an unqualified hottest possible temperature.
NIST — 2022 CODATA fundamental constants
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 Planck temperature: This is a theoretical value calculated under stated physical assumptions, not a direct observation.
Compare temperature differences in kelvins; Celsius and Fahrenheit ratios are not meaningful.
