How do I convert degrees Rankine back to kelvins?

Use the reverse converter: 1 degree Rankine equals 0.555556 K.

Is this converter accurate?

Yes. It uses the exact SI/NIST definitions of each unit and shows up to 6 significant digits.

To convert kelvins to degrees Rankine, use the formula °R = K × 9/5.

°R = K × 9/5

150 K → °R = K × 9/5 → 270 °R

Kelvin and Rankine start at absolute zero, so negative values are physically impossible.

Kelvin (K): The SI base unit of temperature, with zero at absolute zero. Named after Lord Kelvin and used in physics and chemistry.
Degree Rankine (°R): An absolute scale using Fahrenheit-sized degrees, zero at absolute zero. Used in some US thermodynamics and engineering work.
