 Question 495

 What is the Reaumur Scale for temperature and how does it compare to degrees F, C, and K?
The Reaumur Scale was created in 1730 by French scientist Rene-Antoine Ferchault de Reaumur, who set 0 R as the freezing point of water and 80 R as the boiling point of water. Though in common use for a time, the Reaumur Scale had more or less disappeared by the end of the eighteenth century. Each degree R is equal to 5/4 of a degree C, so T(C)=T(R)*5/4. Similarly, T(F)=T(R)*9/4+32 and T(K)=T(R)*5/4+273.15.
