To convert from degrees Celsius into degrees Rankine, add
273.15, multiply by 9, and divide by 5. For example, 0 degrees
Celsius is equal to (0 + 273.15) = 273.15 x 9 = 2458.35 / 5 =
491.67 degrees Rankine.
R = 9/5 (C + 273.15)
For every additional degree Celsius, the difference between
Rankine and Celsius increases by 9 / 5 = 1.8 degrees - the same
amount as it increases for x+1 degrees Fahrenheit.
Here is a small table:
0 degrees C = 491.67 Rankine.
1 degree C = 493.47 Rankine.
2 degrees C = 495.27 Rankine.
Similarly, for every increase of one degree Fahrenheit, the
number of degrees Rankine increases by 1.
For example:
32 Fahrenheit = 491.67 Rankine
33 Fahrenheit = 492.67 Rankine.
To convert Celsius to Rankine, first convert Celsius to Kelvin
by adding 273.15, then multiply by 9/5 or by 1.8 to get the Rankine
temperature.
R = 9/5 (C + 273.15)
*Rankine is the Fahrenheit temperature scale re-adjusted to
start at absolute zero, so it is also the Fahrenheit temperature
plus 459.67 degrees. -459.67°F = 0 R
