Quick Conversion Tip
Multiply Kelvin by 1.8 for Rankine.
Unit Definitions
Kelvin (K)
Absolute SI temperature scale starting at absolute zero.
Multiply Kelvin by 9/5 to reach Rankine. Convert Kelvin to Celsius by subtracting 273.15 and to Fahrenheit with (K − 273.15) × 9/5 + 32.
Rankine (°R)
Absolute temperature scale with Fahrenheit-sized degrees.
To Kelvin, multiply by 5/9. To Fahrenheit, subtract 459.67. To Celsius, subtract 491.67 then multiply by 5/9.
Common Use Cases
- Gas constant unit conversions.
- Combining SI and US thermo tables.
- Engineering coursework.
- Absolute temperature ratios.
Understanding the Conversion
°R = K × 9/5. Same zero, different degree size.
0 K = 0°R · 273.15 K = 491.67°R · 373.15 K = 671.67°R.

FAQs
How do you convert Kelvin to Rankine?
Multiply by 9/5 (1.8).
Do K and °R share absolute zero?
Yes—0 K = 0°R; only the degree size differs.
Kelvin to Fahrenheit via Rankine?
K × 9/5 = °R, then °R − 459.67 = °F.
