How do you convert Rankine to Kelvin?

To convert Rankine to Kelvin, one must understand the relationship between the two temperature scales. The Rankine scale is an absolute temperature scale used in thermodynamics, where zero Rankine (0°R) represents absolute zero, similar to 0 Kelvin (K).

To perform the conversion, it is essential to realize that the increment size for Rankine degrees is the same as that for Fahrenheit degrees. Therefore, to convert a temperature from Rankine to Kelvin, you must first account for the absolute zero point difference and then convert the temperature scale.

The conversion formula is:

1. First, convert Rankine to Fahrenheit by noting that the Rankine scale is offset from the Fahrenheit scale (°R = °F + 459.67).

2. From Fahrenheit, you can convert to Kelvin using the relation where 0°F equals 255.37K.

3. However, a simpler approach skips directly to Rankine, knowing that the absolute scale (Kelvin) can be reached from Rankine by multiplying by the conversion factor of 5/9 (since Kelvin is defined in a scale that uses the Celsius scale which is 5/9 of the Fahrenheit scale).

Therefore, if you take a reading in Rankine and multiply it by
