केल्भिन तापक्रम परिवर्तन सुत्र
Conversion from to सुत्र
केल्भिन डिग्री सेल्सियस °से = के - २७३.१५
डिग्री सेल्सियस केल्भिन के = °से + २७३.१५
केल्भिन डिग्री फरेनहाइट °फ = के × १.८ − ४५९.६७
डिग्री फरेनहाइट केल्भिन के = (°फ + ४५९.६७) / १.८
Note that for temperature intervals rather than temperature readings,
1 K = 1 °C and 1 K = 1.8 °F

केल्भिन (अङ्ग्रेजीमा kelvin, symbol: K) तापक्रम नाप्ने एस्.आई. ईकाई हो, र सात एस्.आई. आधार ईकाई मध्येको एक हो। यसलाई दुई तथ्यले ब्याख्या गर्दछ: शुन्य केल्भिन is absolute zero (when molecular motion stops), and one kelvin is the fraction 1/273.16 of the thermodynamic temperature of the triple point of water. The Celsius temperature scale is now defined in terms of the kelvin, with 0 °C corresponding to 273.15 kelvins, approximately the melting point of water under ordinary conditions.

The kelvin is named after the British physicist and engineer William Thomson, 1st Baron Kelvin; उनका barony was in turn named after the River Kelvin, which runs through the grounds of the University of Glasgow.

Typographical conventions

The word kelvin as an SI unit is correctly written with a lowercase k (unless at the beginning of a sentence), and is never preceded by the words degree or degrees, or the symbol °, unlike degrees Fahrenheit, or degrees Celsius. This is because the latter are adjectives, whereas kelvin is a noun. It takes the normal plural form by adding an s in English: kelvins. When the kelvin was introduced in 1954 (10th General Conference on Weights and Measures (CGPM), Resolution 3, CR 79), it was the "degree Kelvin", and written °K; the "degree" was dropped in 1967 (13th CGPM, Resolution 3, CR 104).

Note that the symbol for the kelvin unit is always a capital K and never italicised. There is a space between the number and the K, as with all other SI units.

Unicode includes the "kelvin sign" at U+212A (in your browser it looks like K). However, the "kelvin sign" is canonically decomposed into U+004B, thereby seen as a (preexisting) encoding mistake, and it is better to use U+004B (K) directly.

Conversion factors

Kelvins and Celsius

The Celsius temperature scale is now defined in terms of the kelvin, with 0 °C corresponding to 273.15 kelvins.

  • kelvins to degrees Celsius

Temperature and energy

In a thermodynamic system, the energy carried by the particles is proportional to the absolute temperature, where the constant of proportionality is the Boltzmann constant. As a result, it is possible to determine the temperature of particles with a certain energy; or to calculate the energy of particles at a certain temperature:

  • kelvins to electron volts
