Delisle to Kelvin Conversion
Converting Delisle (°De) to Kelvin (K) is a common temperature conversion. 1 °De equals 372.483333 K. For example, 100 °De is equal to 306.483333 K.
Quick Mental Math: Delisle to Kelvin
Divide by 1.50 to convert delisle to kelvin.
Why is converting Delisle to Kelvin tricky?
Kelvin has a different zero point (273.15), so you can't just multiply or divide.
Reference Temperatures
Absolute zero: 559.725 °De = 0 K. Water freezing point: 150 °De = 273.15 K. Room temperature: 120 °De = 293.15 K. Body temperature: 94.5 °De = 310.15 K. Water boiling point: 0 °De = 373.15 K.
What is Delisle?
Delisle (°De) is a unit of temperature. The Delisle scale measures temperature with zero at the boiling point of water and increasing values downward. One degree Delisle equals 2/3 of a degree Celsius, making it inversely proportional to Celsius. This scale is now mostly historical and not used in modern thermometry [cgpm-resolutions]. Invented by Joseph-Nicolas Delisle in 1732, the scale was devised for scientific observations in Russia. It fixed 0 °De at 100 °C (water boiling point) and increased toward freezing point, opposite to Celsius. The scale fell out of use in favor of Celsius and Kelvin as international standards emerged [cgpm-resolutions]. The Delisle scale is obsolete and retained only in historical scientific texts and specialized archival references. Modern temperature measurements universally use Celsius, Fahrenheit, or Kelvin. Organizations like BIPM do not recognize Delisle for current temperature calibration [bipm-si-brochure].
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: Delislee, Delisleu, Delisell, Delislee scale, Delisle temperature, kelvin degree, kelvins, kelvins unit, kelvian, kelvins scale. All of these refer to the Delisle to Kelvin conversion.
