RÝmer is a disused temperature scale named after the Danish astronomer Ole Christensen RÝmer, who proposed it in 1701.
In this scale, the zero was initially set using freezing brine. The boiling point of water was defined as 60 degrees. RÝmer then saw that the freezing point of water fell at roughly one eighth of that value (7.5 degrees), so he used that value as the other fixed point. Thus the unit of this scale, a RÝmer degree, is 40/21sts of a kelvin (or of a Celsius degree). The symbol is sometimes given as įR, but since that is also sometimes used for the Rankine scale, the other symbol įRÝ is to be preferred. The name should not be confused with Rťaumur.
Daniel Gabriel Fahrenheit learned of RÝmer's work and visited him in 1708; he improved on the scale, increasing the number of divisions by a factor of four and eventually establishing what is now known as the Fahrenheit scale, in 1724.
