The Rankine and Kelvin scales are both absolute temperature scales, meaning they begin at absolute zero, the point where all molecular motion ceases. While Kelvin is the SI unit for temperature, the Rankine scale is sometimes used in engineering and thermodynamics, particularly in the United States. This guide will delve into the Rankine to Kelvin conversion and provide a simple method for performing this calculation.
The Rankine scale, named after Scottish engineer William John Macquorn Rankine, is an absolute thermodynamic temperature scale where absolute zero is defined as 0°R. The size of one degree Rankine is equal to one degree Fahrenheit.
The Kelvin scale is the SI unit of temperature. It is also an absolute scale, with absolute zero defined as 0 K. The size of one Kelvin is equal to one degree Celsius.
The simple formula to convert Rankine to Kelvin is:
**Kelvin (K) = Rankine (°R) * (5/9)**
Let's convert 500°R to Kelvin:
