Discrepancy in Rankine section

This comment was originally posted at the talk page of the now deleted Fahrenheit and Rankine temperatures article and kept here for archival purposes.

The article says this:

it is based on one degree Rankine being equal to one degree in the Rankine scale is absolute zero...The melting point of water in the Rankine scale is 491.67 °R and the normal boiling point of water is 671.67 °R (i.e., 459.67 + 212).

This makes no sense. If one °R= one °F, wouldn't the melting point of water be −491.67. Oh. Nevermind. I see where I went wrong...Drew R. Smith 04:15, 14 June 2009 (UTC)

Drew, I'm glad that you found the article to be correct and happy that someone has at least read it. Oh, and thanks for correcting my redundant word "been". Milton Beychok 04:53, 14 June 2009 (UTC)
