### Kelvin to Rankine Conversion Formula

Reverse formula and conversion (Rankine to Kelvin)

### 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**".

### Rankine

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.
