Example: 27° Rankine = -258.15° Celsius

About these units

Rankine: The degree Rankine (°R) is an absolute temperature scale using Fahrenheit-sized increments.

Celsius: The degree Celsius (°C) is the SI-derived unit of temperature. It is defined so that 0 °C = 273.15 K exactly, with the same unit increment as the kelvin.
