Temperature conversion derivation
Convert K to Kelvin first, then convert from Kelvin to °R. Temperature scales use both scaling and offset, so a single multiplicative factor is not enough.

Why the K to °R conversion factor holds
The conversion factor from Kelvin (K) to Rankine (°R) is 1.8. This factor holds because both are absolute temperature scales related by a direct multiplicative relationship, using the same base unit. The formula °R = K × 9/5 defines this conversion.
Definition
The Kelvin (K) is an absolute thermodynamic temperature scale. The Rankine (°R) is an absolute temperature scale with Fahrenheit-sized degrees. The conversion uses the factor 1.8, equivalent to 9/5.
Principle
The conversion factor is derived from the definition linking the two absolute scales. Since both scales measure temperature, their ratio is constant. The forward factor is 1.8, and the reverse factor is 0.5555555555555556, which is 5/9.
Assumptions
- Both scales are absolute temperature scales.
- The conversion uses a direct multiplicative factor without an offset.
Cautions
- Note: this conversion depends on a specific unit definition or physical assumption. Check the context before using it in reports.
