rømer temperature scale

In this scale, the zero was initially set using freezing brine. Rømer's temperature scale was based on the boiling point of water being 60 degrees - astronomers are used to dividing things by 60, seeing as space is divided up this way into arcminutes and seconds. Although the Rømer scale is no longer in use, it is of some historical importance, because it was one of the first calibrated scales. The Rømer scale (Danish pronunciation: [ˈʁœˀmɐ]; notated as °Rø), also known as Romer or Roemer, is a temperature scale named after the Danish astronomer Ole Christensen Rømer, who proposed it in 1701. Thus the unit of this scale, a Rømer degree, is 100/52.5 = 40/21 of a kelvin or Celsius degree. Thus the unit of this scale, a Rømer degree, is 100/52.5 = 40/21 of a kelvin or Celsius degree. The Rømer scale is no longer in use, but it is of some historical importance. It is an empirical scale that was developed by a historical progress, which led to its zero point 0 °C being defined by the freezing point of water, and additional degrees defined so that 100 °C was the boiling point of water, both at sea-level atmospheric pressure. Rømer 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. Rømer set 0 = salt-ice water freezing, 1 = boiling water, divided into 60 degrees, Fahrenheit built a thermometer that made Rømer's degrees too big, so he quartered them, and used a colder cold (basically the refigeration is at 0 °F). [2][3], Daniel Gabriel Fahrenheit, inventor of the Fahrenheit scale, learned of Rømer's work and visited him in 1708. [2][3], Daniel Gabriel Fahrenheit, inventor of the Fahrenheit scale, learned of Rømer's work and visited him in 1708. The boiling point of water was defined as 60 degrees.
