1 Kelvin = 1.8 Rankine
Key Formulas
Celsius → Fahrenheit
°F = f(°C)Fahrenheit → Celsius
°C = f(°F)Celsius → Kelvin
K = f(°C)Kelvin → Celsius
°C = f(K)Formula
°R = K × 1.8Kelvin and Rankine are both absolute temperature scales — they start at absolute zero. The difference is degree size: 1 K = 1.8°R (since Rankine uses Fahrenheit's degree size). This simple multiplication converts between the two absolute scales.
