About the units
Degree Rankine (°R)
The Rankine scale starts at absolute zero, like the kelvin, but uses degrees the size of Fahrenheit degrees. It appears in some US engineering work.
Kelvin (K)
The kelvin is the SI unit of temperature. It starts at absolute zero, so 0 K is −273.15 °C, and one kelvin is the same size as one degree Celsius.
