Celsius (abbreviations: C, or °C, or deg C): also known as centigrade, is a SI metric scale and unit of measurement for temperature and used by most countries in the world. It is named with regard to the Swedish astronomer Anders Celsius (1701–1744), who developed a similar temperature scale.
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 Celsius to Degree Rankine
Example: How many degree Rankine are equivalent to 69.22 degree Celsius?
As;
1 degree Celsius = (X+273.15)*(9/5) degree Rankine
69.22 degree Celsius = Y degree Rankine
Assuming Y is the answer, and by substitution principle;
Y equals ( (69.22+273.15)*(9/5) ) over 1, where X is substituted by 69.22
(i.e.) Y = ( (69.22+273.15)*(9/5) ) / 1 = 616.266 degree Rankine
Answer is: 616.266 degree Rankine are equivalent to 69.22 degree Celsius.
