That reading is below absolute zero (-273.15°C / -459.67°F / 0 K) -
no physical temperature can be that low.

Rankine keeps Fahrenheit-size steps above absolute zero
Rankine is useful in US thermodynamics and heat-transfer work. Use it when an equation requires absolute temperature but the surrounding measurements use Fahrenheit-size degrees.

Calculation method for Kelvin and Rankine
°R = K × 1.8
Kelvin and Rankine are the two absolute scales - both put 0 at absolute zero - so converting between them is pure scaling: multiply kelvins by 1.8 to get Fahrenheit-sized Rankine degrees. No offsets involved.
Need the calculation the other way around? Use the Rankine to Kelvin converter, or compare all scales in the temperature conversion calculator.
Worked examples with real reference points
- Convert 300 K: 300 × 1.8 = 540 °R
- Convert 273.15 K: 273.15 × 1.8 = 491.67 °R (water freezes)
Questions about the scales and engineering use
Is 0 K the same as 0 °R?
Yes - both scales place zero exactly at absolute zero. Only the degree size differs (1 K = 1.8 °R).
