This did not greatly change the scale but made it easier to calibrate by defining it by reference to pure water. Line: 24 The Rømer scale(Danish pronunciation: [ˈʁœˀmɐ]; notated as °Rø), also known as Romeror Roemer, is a temperaturescale named after the DanishastronomerOle Christensen Rømer, who proposed it in 1701. It will enhance any encyclopedic page you visit with the magic of the WIKI 2 technology. Alongside the Newton scale, it was the first calibrated scale. Rømer ( Danish pronunciation: [ ˈʁœːˀmɐ] (also Roemer) is a temperature scale named after the Danish astronomer Ole Christensen Rømer, who proposed it in 1701. Newton's system was calibrated between the freezing point of water (0 degrees) and human body temperature (12 degrees); it was a coarser scale, but unlike Rømer's it was not intended for everyday use, as Newton's interest was in determining the boiling points of metals, which are not readily accessible with Rømer's system based on liquid thermometers. This avoided the drawbacks of both the low boiling point of pure alcohol and the extreme non-linearity of pure water near freezing. In this scale, the zero was initially set using freezing brine.
