Converting Rankine to Fahrenheit
Rankine is an absolute temperature scale based on the Fahrenheit scale. Fahrenheit is a relative temperature scale. The Rankine scale is normally only used in the United States because of the popularity of the Fahrenheit scale.
Conversion between Rankine and Celsius is very easy... simply subtract 459.67.
For example, suppose you are converting 600 Rankine. Subtract 459.67 from it which makes 140.33°F.
About Rankine
Rankine is temperature unit normally used in thermodynamics. It is named after the Scottish engineer and physicist William John Macquorn Rankine, who is know for his work in thermodynamics. The Rankine scale is based on the Fahrenheit scale with degree increments identical but starting at absolute zero.
With the zero point at absolute zero (-459.67°F) it is easy to convert between Rankine and Fahrenheit: simply subtract 459.67.
The Rankine scale is not normally used in everyday life as it is an engineering unit particularly thermodynamics in the United States.
About the Fahrenheit scale
Fahrenheit is a relative temperature scale created by the Polish-German physicist Daniel Gabriel Fahrenheit. It is mainly used in the United States and is less common in science compared to the Celsius (or Centigrade) scale.
Fahrenheit is based on the freezing and boiling points of water at standard atmospheric pressure with 32°F at freezing point and 212°F at boiling point.
Whilst Fahrenheit is still commonly used in the United States it is important to note that most of the world relies on Celsius.
