Explanation

To convert degrees Rankine to degrees Fahrenheit subtract 459.67.

Formula

°Ra − 459.67=°F

The degree Rankine (°Ra) is a unit of temperature.

Definition

The zero of the Rankine scale absolute zero and a temperature difference of one degree Rankine is equal to one degree Fahrenheit.

History

The Rankine scale was first proposed in 1859 by Macquorn Rankine, a scottish mechanical engineer. It follows the same logic as the kelvin scale which was suggested in 1848. The only difference between the two is the definition of the steps. The Kelvin scale uses steps in Celsius when the Rankine scale uses steps in Fahrenheit.

The degree Fahrenheit (°F) is a unit of temperature.

Definition

The Fahrenheit scale uses the freezing and boiling point of water as fixed reference points. The values associated to these two points are 32 °F and 212 °F respectively.

History

In its original proposal in 1724, Fahrenheit used the temperature of a solution of brine to set the 0 of his scale and the average temperature of the human body was set at 96 °F. 32 °F was marked as the temperature of freezing water.

Following the work of Anders Celsius, the Fahrenheit scale was redefined in 1776 to the present definition. This redefinition changed the temperature of the original solution of brine to approximately 4 °F and the average human body temperature to 98.6 °F.
