Degrees Rankine to Kelvin (°R to K)
Convert degrees Rankine to kelvin with the formula K = °R × 5/9. Conversion table and worked examples, with JSON API and MCP access.
Formula
K = °R × 5/9
K = °R × 5/9 — reverse: °R = K × 9/5
Non-linear conversion: the formula above is applied directly (no single multiplication factor).
Worked examples
- 300 °R = 166.667 K
- 273.15 °R = 151.75 K
- 0 °R = 0 K

FAQ
What is the formula to convert degrees Rankine to kelvin?
K = °R × 5/9. For example, 300 °R = 166.667 K.
How do I convert kelvin back to degrees Rankine?
°R = K × 9/5; the kelvin-to-degrees Rankine page applies it directly.
Why is there no single multiplication factor?
Temperature scales have different zero points, so the conversion is an affine formula (scale and offset), not a plain multiplication.
