1,500 degrees Celsius
1,773 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.

Molten iron
Molten iron is iron in its liquid state, formed by heating solid iron above its melting point.
1,811 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
1,500 degrees Celsius is 37.85 K lower than the temperature of molten iron.

1,500 degrees Celsius
Temperature: 1,773 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.
Molten iron
Temperature: 1,811 K; defined reference.
An approximate melting-temperature reference for pure iron; alloys behave differently.
Defined examples — our methodology
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 temperature of molten iron: 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.
