The **Rankine scale**(symbolized as **°R** or **Ra**) is an absolute temperature scale used in some technical fields, particularly in thermodynamics in the United States. **1 °R corresponds to -272.59 °C.**

A temperature on the Rankine scale corresponds to the value on the Fahrenheit scale minus 459.67 °F. Converting Rankine to other temperature units is not complicated, but it is important to know the appropriate conversion factors.

## Rankine to Fahrenheit

To convert temperatures from Rankine to Fahrenheit, the following formula is used: **T(°F) = T(°R) - 459.67**

Example: If the temperature in Rankine is 600 °R, then the temperature in Fahrenheit is: 600 °R - 459.67 °F = 140.33 °F

## Rankine to Celsius

The conversion from Rankine to Celsius takes place in two steps. First convert Rankine to Fahrenheit and then Fahrenheit to Celsius:

1. conversion from Rankine to Fahrenheit (as shown above).

2. conversion from Fahrenheit to Celsius: **T(°C) = (T(°F) - 32) × (5/9)**

Example: For a temperature of 600 °R:

First in Fahrenheit: 600 °R - 459.67 °F = 140.33 °F

Then in Celsius: (140.33 °F - 32) × (5/9) = 60.18 °C

## Rankine in Kelvin

Two steps are also required here:

1. conversion from Rankine to Celsius (as shown above).

2. conversion from Celsius to Kelvin: **T(K) = T(°C) 273.15**

Example: For a temperature of 600 °R:

First in Celsius: 60.18 °C

Then in Kelvin: 60.18 °C 273.15 = 333.33 K

## Summary

The Rankine scale is not widely used in many parts of the world, but is still in use in certain technical areas in the USA. It is important to be accurate and careful when converting to other temperature units. However, using the formulas above, conversion between Rankine and common temperature units should not be a problem.
