About these units
°R (degrees Rankine): Absolute Fahrenheit scale used in US thermodynamics.
K (kelvin): The SI absolute temperature scale; zero is absolute zero.
Temperature scales have different zero points, so these conversions add or subtract an offset, not just multiply. A temperature difference converts differently: a change of 1 °C equals a change of 1 K and 1.8 °F.
