What is the formula to convert kelvins to degrees Rankine?

°R = (K × 1 + 0 − 0) ÷ 0.555556. For example, 100 K = 180 °R.

Is converting kelvins to degrees Rankine just multiplication?

No — kelvins and degrees Rankine have different zero points, so you apply a formula rather than a single factor. For example, 100 K = 180 °R.

What is 100 K in °R?

100 K = 180 °R. Plugging any K value into the formula °R = (K × 1 + 0 − 0) ÷ 0.555556 gives the result in °R.

Temperature

Celsius, Fahrenheit, Kelvin — three zeros, three worlds

Fahrenheit's zero was a slurry of ice, water and sal ammoniac, reproducible in an Amsterdam workshop. Celsius's zero meant boiling water for three years. Kelvin's zero is a limit the universe never crosses. Three scales, and three entirely different answers to the question of where counting heat should begin.
