Frequently asked questions
What is the source unit in this conversion?
The source unit is Kelvin (K). Kelvin is the SI absolute temperature scale, where 0 K is absolute zero.
What is the destination unit in this conversion?
The destination unit is Rankine (°R). Rankine is an absolute temperature scale that uses Fahrenheit-sized degrees.
How do I convert Kelvin to Rankine?
Use the formula °R = K × 9/5. For example, converting a sample value follows the same equation shown in the conversion table above.
Is the Kelvin to Rankine conversion exact?
Yes. The relationship between the two scales is a fixed linear equation, so the conversion is mathematically exact with no rounding of constants.
Where is this conversion commonly used?
Temperature conversions like this one appear in science, engineering, weather reporting, and historical or regional references that still use Rankine.
Can I convert Rankine back to Kelvin?
Yes. Use the reverse formula K = °R × 5/9 to convert Rankine back to Kelvin.

About this conversion
This page converts Kelvin (K) into Rankine (°R), two scales used to measure temperature.
Kelvin to Rankine conversions come up in science, engineering, weather reporting, and historical references, depending on which scale is in use.
The formula is °R = K × 9/5, a linear equation that accounts for both the scale factor and the zero-point offset between the two scales.
The conversion is exact: it uses fixed constants defined by the relationship between the two scales, not a measured or approximate factor.
Kelvin is the SI absolute temperature scale, where 0 K is absolute zero. Rankine is an absolute temperature scale that uses Fahrenheit-sized degrees.
