°C:
Celsius is the temperature scale previously known as the centigrade scale.
The name Centigrade was derived from the Latin - meaning "hundred degrees".
When Anders Celsius - a Swedish astronomer - created his original scale in 1742 he inexplicably chose 0° for the boiling point and 100° for the freezing point.
One year later Frenchman Jean Pierre Cristin proposed an inverted version of the scale - freezing point 0°, boiling point 100°.
He named it Centigrade.
In 1948, by international agreement, Cristin's adapted scale became known as Celsius to honour the Swedish Scientist.
The degree Celsius - symbol: °C - can refer to a specific temperature on the Celsius scale as well as serve as unit increment to indicate a temperature interval.
°Rø:
The Rømer scale (Danish pronunciation: [ˈʁœːˀmɐ]; 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.
It is based on the freezing point of pure water being 7.5 degrees and the boiling point of water as 60 degrees.
Daniel Gabriel Fahrenheit, inventor of the Fahrenheit scale, learned of Rømer's work and visited him in 1708. Fahrenheit described how he borrowed the idea for his scale from this visit, but increased the number of divisions.
Newton published his scale in the same year as Rømer. 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.
By the way, to convert between Celsius and Rømer, you can use this application so easily. So if you need it, download and use it by now.
