T(oR) = 1.8 * T(K)
just divide Rankine temperature by 1.8 to get temperature in Kelvin
ºK = (ºR - 491.67) / 1.8 + 273.15
T(oR) = 1.8*T(K)
multiply by 9/5 (1.8)
It depends on whether you want to convert it to Kelvin, Fahrenheit, Rankine, Reaumur, etc. The method of conversion is different in each case.
ANSWER I use free online temperature converter it can convert Fahrenheit, Celsius, Kelvin, Rankine, Reaumur, Newton, Romer, Delisle
Rankine. Rankine is a temperature scale that is used alongside Fahrenheit, where 0 Rankine is absolute zero and each degree Rankine is equal to a degree Fahrenheit.
Formulas for conversion are: R = F + 459.67 F = R - 459.67
Use this equation to convert Celsius to Rankine: ºR = (ºC x 1.8) + 491.67
Kelvin and Rankine
Kelvin is a unit of temperature in the International System of Units (SI), based on the absolute zero point, where 0K is absolute zero. Rankine is a unit of temperature in the Imperial system, also based on absolute zero, where 0°R is absolute zero. The main difference is the scale used for measurement (Celsius for Kelvin and Fahrenheit for Rankine).
Fahrenheit,Celsius, Kelvin don't forget Rankine.
In Celsius: 0.5556 In Kelvin: 273.71 In Rankine: 492.67
