Definitions:

Kelvin (abbreviations: K, or °K, or deg K): is a unit of measure for temperature based upon an absolute scale, thermodynamic temperature scale using as its null point absolute zero, the temperature at which all thermal motion ceases in the classical description of thermodynamics. It was first proposed in 1848 and is one of the seven base units in the International System of Units (SI).

Rankine (abbreviations: R, or °R, or deg R): is a thermodynamic temperature based on an absolute scale named with regard to the Glasgow University engineer and physicist William John Macquorn Rankine, who proposed it in 1859.

## How to Convert Degree Kelvin to Degree Rankine

### Example: How many degree Rankine are equivalent to 5.04 degree Kelvin?

As;

1 degree Kelvin = (9/5)*X degree Rankine

5.04 degree Kelvin = Y degree Rankine

Assuming Y is the answer, and by substitution principle;

Y equals ( (9/5)*5.04 ) over 1, where X is substituted by 5.04

(i.e.) Y = ( (9/5)*5.04 ) / 1 = 9.072 degree Rankine

Answer is: 9.072 degree Rankine are equivalent to 5.04 degree Kelvin.
