Temperature converter
Celsius, Fahrenheit, kelvin and Rankine, all four scales side by side, and readings below absolute zero rejected.
Result
32 °F
- Formula
- 0 °C = 32 °F (non-proportional conversion)
Note
The four rulers share one axis starting at absolute zero, where only two scales put their zero. Two of them pack their graduations in the ratio 5/9.
Calculation, assumptions and sources
OverviewA temperature converted between Celsius, Fahrenheit, kelvin and Rankine.
A temperature converted between Celsius, Fahrenheit, kelvin and Rankine. Celsius and Fahrenheit carry a zero offset as well as a scale factor. A value below absolute zero is rejected, whichever scale it is entered in.
Method & formulasK = °C + 273.15
Kelvin and Rankine are absolute scales: their zero is absolute zero. Celsius and Fahrenheit shift that zero by convention, to the freezing point of water for the former, to another historical reference for the latter.
