Why is converting Rømer to Celsius tricky?
The conversion factor requires careful attention to avoid reversing the operation.
Reference Temperatures
Absolute zero: -135.90375 °Rø = -273.15 °C. Water freezing point: 7.5 °Rø = 0 °C. Room temperature: 18 °Rø = 20 °C. Body temperature: 26.925 °Rø = 37 °C. Water boiling point: 60 °Rø = 100 °C.
What is Rømer?
Rømer (°Rø) is a unit of temperature. The Rømer scale is an early temperature scale where water freezes at 7.5 °Rø and boils at 60 °Rø. It was devised to improve temperature measurement accuracy using mercury thermometers. One degree Rømer equals approximately 1.25 degrees Celsius [cgpm-resolutions]. Ole Christensen Rømer introduced this scale in 1701 to standardize temperature readings using mercury thermometers. It influenced later scales such as Celsius and Fahrenheit, representing an important step in temperature measurement history [cgpm-resolutions]. The Rømer scale is obsolete and used only for historical study. It has no current application in science or industry but remains significant in the chronology of temperature scale development [cgpm-resolutions].
What is Celsius?
Celsius (°C) is a unit of temperature. Celsius is a temperature scale where 0 °C is the freezing point and 100 °C is the boiling point of water at standard atmospheric pressure. It is defined by the International System of Units (SI) and related to the Kelvin scale by the formula °C = K − 273.15 [cgpm-resolutions]. The Celsius scale was developed by Anders Celsius in 1742. It became internationally accepted and officially incorporated into the SI temperature scales by the CGPM in 1948 for scientific and everyday temperature measurement [cgpm-resolutions]. Celsius is the standard temperature unit for most countries worldwide, including Canada, Europe, and Australia. It is used in weather forecasts, scientific research, and industrial processes as endorsed by ISO and BIPM [bipm-si-brochure].
Common Misspellings
People often search for this conversion using these alternate spellings: romer scale, roemer, romer temperature, römer, celcius, celsious, celcius, celsius degree. All of these refer to the Rømer to Celsius conversion.
