How do I convert Rankine (°R) to Kelvin (K)?

1 rankine equals 0.555556 kelvin using SI-based conversion and precise factors.

What is the formula to convert Rankine (°R) to Kelvin (K)?

Temperature conversions include an offset (e.g., +273.15 for K, or +/−32 with ratio 5/9 and 9/5).

Yes, it follows an exact affine transformation between scales (ratio + offset).

Temperature scales combine ratios and offsets; Kelvin is absolute.

Rankine (°R)

Absolute scale in °F increments.

History: Proposed by William Rankine in 19th c.

Kelvin (K)

Absolute thermodynamic scale; SI base unit.

History: Defined via Boltzmann constant since 2019.
