Enter the temperature in kelvin in the top field, then press the 'Convert' button. Alternatively, you can convert from Rankine to kelvin by entering the value in Rankine in the bottom field and press 'Convert'.

Reverse formula and conversion (Rankine to Kelvin)

Kelvin is the unit of measure for temperature adopted by the **International System of Units**. **Absolute zero is 0 K**, equivalent to -273.15 °C. Kelvin uses the same interval as Celsius. The Kelvin scale is named after **Baron Kelvin of Largs**, who described the need for an absolute thermometric scale in his paper "**On an Absolute Thermometric Scale**".

The Rankine scale is named after Scottish physicist **William John Macquorn Rankine**. Similarly to kelvin **absolute zero is 0 °R**, equivalent to -459.67 °F. Rankine uses the same interval as Fahrenheit.
