1,000 degrees Celsius
1,273 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.

Lava
Lava is molten rock that erupts from a volcano and flows on the Earth's surface before cooling and solidifying.
1,373 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.
A little perspective
1,000 degrees Celsius is 100 K lower than the temperature of lava.

- 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 temperature of lava: This is an illustrative comparison value, not a claim that every example is the same.
Compare temperature differences in kelvins; Celsius and Fahrenheit ratios are not meaningful.
