Convert rankine to kelvin Online

Convert Temperature Units Online with Rankine (°R) to Kelvin (K) Conversion

Convert Rankine to Kelvin using the exact conversion factor. This page provides the formula, reference values, and practical context for engineering, technical calculations, and professional measurement use.

Conversion Formula

K = °R × 5/9

Temperature conversions use an offset formula, not a single multiplier. Apply the relationship shown above (for example Rankine (°R) to Kelvin (K)) so absolute scale differences (such as the 273.15 K offset for Celsius) are handled correctly.

Example

Convert 1 R to K.

  • Step 1: Write the formula: K = °R × 5/9
  • Step 2: Substitute: R = 1
  • Step 3: Result: 0.555556 K
So, 1 R = 0.555556 K.
