How to Convert Rankine to Kelvin
To convert Rankine (°R) to Kelvin (K), use the formula: K = °R × 5/9.
For example, to convert 5 °R to K: 5 °R = 2.7778 K. Similarly, 10 °R = 5.5556 K, 25 °R = 13.8889 K, and 100 °R = 55.5556 K.
To convert in the other direction, 1 K = 1.8 °R. Simply enter your value in either field above for instant bi-directional conversion.
What is a Rankine?
Rankine (°R) is an absolute temperature scale using Fahrenheit-sized degrees, starting at absolute zero. Rankine is used in some US engineering contexts, particularly in thermodynamics.
What is a Kelvin?
Kelvin (K) is the SI base unit of temperature, starting at absolute zero (−273.15 °C). Kelvin is used in science, engineering, and color temperature for lighting and displays.
