Kelvin to Degrees Rankine (K to °R)
Convert kelvin to degrees Rankine with the formula °R = K × 9/5. Conversion table and worked examples, with JSON API and MCP access.
Formula
°R = K × 9/5
°R = K × 9/5 — reverse: K = °R × 5/9
Non-linear conversion: the formula above is applied directly (no single multiplication factor).
Worked examples
- 300 K = 540 °R
- 273.15 K = 491.67 °R
- 0 K = 0 °R

FAQ
What is the formula to convert kelvin to degrees Rankine?
°R = K × 9/5. For example, 300 K = 540 °R.
How do I convert degrees Rankine back to kelvin?
K = °R × 5/9; the degrees Rankine-to-kelvin 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.
