This page states "A temperature of 459.67 °F is precisely equal to 0 °R" ... Shouldn't that be the other way around?

yes, fixed --JD79 19:02, 30 January 2007 (UTC)[reply]

Agreed. now it said "A temperature of negative -459.67 °F is precisely equal to 0 °R." - now having the term 'negative' and the sign '-' in their is double negation and would result in the same thing as the above quote. I therefore removed the word negative. Regards, Dola chi-Trei, Trimbir. —Preceding unsigned comment added by 80.140.249.201 (talk) 20:22, 17 September 2007 (UTC)[reply]

Is this scale really disused? I know it's antiquated, but I had a fluids class that encouraged being "bilingual" and so Rankine was used extensively.


I tend to agree - edited accordingly and added link to Rankine cycle - which is important.

I was told by my college Chemistry professor that Rankine was at one time widely used in US industry. --anonymous

The key is at one time. This unit is now obsolete, and mentioned here for completeness. -- Egil 09:26, 15 Feb 2005 (UTC)

Nonsense. Degrees Rankine, unlike some of the other obsolete degrees mentioned in the other articles, are still used. Gene Nygaard 10:25, 15 Feb 2005 (UTC)
If you insist, let me reprashe that: Rankine is antiquated. Really. -- Egil

'A competent scientist should be able to work in any system of units' (A Cavendish Professor of Physics to his flock, in the days when they had cgs, esu, emu, degrees Brix etc.) .


Many chemical engineering, thermodynamics, and heat transfer textbooks, used from Britain to the US to Singapore, use the Rankine scale. It may be antiquated in the same way that any non-metric units are antiquated, but it is still used.

I removed "now rarely used". I use it all the time (to my disappointment)! It is useful in thermodynamics when using US Customary units. — TheKMantalk 23:08, 27 January 2006 (UTC)[reply]

Rankine degrees are still usefull in designing for those living in a Fahrenheit world. It may be antiqudated to acedemics in ivory towers but I use it along with the Stepahan Boltman Equation here in real life in my welding shop on heater designs. The heater ouputs are measured in antiqudated Fahrenheit/Rankine degree units. Most people around here relate to temperature in Fahrenheit degrees. Guess we're all antiqudated but any competent engineer should be able to work in units that the customer relates to. --JTH01 08:52, 14 April 2007 (UTC)[reply]

Chemical Engineering at Imperial College, we have students and books from Europe, Africa, Asia and America. I have yet to see a single person use this scale and I think most people here would consider such a person to have a bizarre death wish. Rankine may be widely used in the United States, but that's a long way from being widely used full-stop. —Preceding unsigned comment added by 129.31.204.157 (talk) 12:54, 12 March 2008 (UTC)[reply]

Rankine cycle is more notable

It should be primary. --JWB 07:41, 14 May 2007 (UTC)[reply]

° degrees

In the text and in one table, the symbol is R. In the other table it is °R. Which one is right? Rankine are degrees like Celsius or are like kelvin?
