Rømer to Kelvin Conversion
Converting Rømer (°Rø) to Kelvin (K) is a common temperature conversion. 1 °Rø equals 260.769048 K. For example, 100 °Rø is equal to 449.340476 K.

Multiply by 1.90 to convert romer to kelvin.
Why is converting Rømer to Kelvin tricky?
Kelvin has a different zero point (273.15), so you can't just multiply or divide.
Reference Temperatures
Absolute zero: -135.90375 °Rø = 0 K. Water freezing point: 7.5 °Rø = 273.15 K. Room temperature: 18 °Rø = 293.15 K. Body temperature: 26.925 °Rø = 310.15 K. Water boiling point: 60 °Rø = 373.15 K.
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 The Rømer scale is obsolete and used only for historical study.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 Kelvin?
Kelvin (K) is a unit of temperature. Kelvin is the SI base unit of thermodynamic temperature defined by fixing the numerical value of the Boltzmann constant to 1.380649×10⁻²³ J·K⁻¹. It uses absolute zero as its null point and increments equal to those of the Celsius scale. One kelvin equals one degree Celsius in magnitude but starts at absolute zero, representing the lowest physically possible temperature [bipm-si-brochure]. The kelvin scale was named after William Thomson, 1st Baron Kelvin, who proposed an absolute thermodynamic temperature scale in 1848. It was formally adopted as an SI base unit in 1967–1968 by the CGPM to provide a universal temperature standard based on fundamental constants [cgpm-resolutions]. Kelvin is the standard temperature unit in scientific research, thermodynamics, and engineering worldwide. It is the official unit for temperature in physics and chemistry according to the International System of Units (SI), used globally including by NIST and BIPM member countries [nist-si-guide].
Common Misspellings
People often search for this conversion using these alternate spellings: romer scale, roemer, romer temperature, römer, kelvin degree, kelvins, kelvins unit, kelvian, kelvins scale. All of these refer to the Rømer to Kelvin conversion.
