What do Rankine and Kelvin Stand for?

Rankine (°R) – The Rankine (°R) scale is identical to the Fahrenheit (°F) scale, and both scales use the same measure unit of temperature. The temperature at which water freezes is 491.67 degree Rankine, while its boiling point is 671.67 degree Rankine.

Kelvin (K) – As part of the International System of Units (SI), the kelvin (K) is the fundamental unit of thermal temperature. The equation of Boltzmann compares it to the triple-point energy of water. 0 K corresponds to absolute zero, which is -273.15 °C, on the Kelvin scale. This point is where thermal motion ceases.

Rankine to Kelvin Questions

Question 1: 

Convert 30 Rankine to Kelvin


The formula to convert Rankine to Kelvin is: 1 °R = 0.5555 K

Given that, Rankine = 30 °R

Now, to get the Kelvin value, substitute the value in the formula.

30 °R = 30 (0.5555) K

30 °R= 16.6666 K

Hence, 30 Rankine = 16.6666 K 

I.e., 30 °R = 16.6666 K

Question 2: 

Convert 140 Rankine to Kelvin.


We know that, 1 °R = 0.5555 K

Given that, Rankine = 140 °R

Substituting the given value in the formula, we get

140 °R = 140 (0.5555) K

140 °R = 77.7777 K

Hence, 140 Rankine is equal to 77.7777 K

I.e., 140 °R = 77.7777 K
