Talk:Rømer scale

message: The Wikipedia articles for all of the other scales are simply titled "Fahrenheit," "Celsius," etc.  This is the only article with "scale" following it.  Is there a reason for this seeming inconsistency, or should it simply be changed to match the others?

(and also tell me how to do it properly).
Anyway, I think there is still a mistake, the whole thing about the factor is that it's a factor
of *divisions*, meaning how many divisions you divide the temperature between freezing 0 C and
boiling 100 C.  Fahrenheit divides it to 180 degrees, Celsius 100 degrees, and Rømer 60 degrees.
So should it not be by factor of 3 (not 4), that is, 3 x 60 = 180 degrees?  —Preceding unsigned comment added by 76.94.59.110 (talk) 01:45, 10 January 2009 (UTC)

replies: text: This seems to be an oversimplification on the part of the source (a medical book, not a physics book).  The real history seems to be somewhat more complicated than that, I'll see if I can't improve it with a better source. However, the factor is greater than three because the zero of the Rømer scale does not correspond to the zero of the Fahrenheit scale. SpinningSpark 17:20, 22 October 2013 (UTC)
thread_title: Still a Mistake

message: In the article, it says -
:"Thus the unit of this scale, a Rømer degree, is 40/21 of a kelvin (or of a Celsius degree)."
However, in the conversion table, it says -
:1 °Rø = 21⁄40 °C
So ... Which is it? Again, this may be an misinterpretation on my part, but it looks a bit confusing.

replies: text: The table has never said that, it says 1 °Rø = 40/21 °C.  What it does say is that to convert Celsius to Rømer [°Rø] = [°C] × 21⁄40 + 7.5 which is also correct.  That does not mean 1 deg Rø = 21/40 deg C.  It means that 1 deg Rø will result if [deg C] = 40/21, which it will after multiplying by 21/40. SpinningSpark 17:05, 22 October 2013 (UTC)
thread_title:  Rømer scale = ... What Celsius? 

message: The "Importance" section includes the text "The idea of using two fiduciary points..." (italics mine). I am unfamiliar with this use of fiduciary and can't find a definition that makes sense of it here. I would change the word if I knew what it was meant to mean!

replies: text: I suppose it means "trusted point" in the sense that mp of ice can be trusted to always occur at the same temperature whereas lowest winter temperature cannot.  A gbboks search turns up a few uses of the term in science (both physics and medicine) to describe a reliably repeatable reference point of some kind, but I didn't find any in connection with a temperature scale.

message: The 'Degree measurements' section in its current form doesn't make sense, as it refers to 'these two points' without establishing what those points are. 1.40.150.55 (talk) 21:29, 9 December 2023 (UTC)
