Kelvinmätning

Kelvinmätning, or Kelvin measurement, refers to the process of determining temperature using the Kelvin scale. The Kelvin scale is an absolute thermodynamic temperature scale, meaning its zero point, absolute zero (0 K), is the theoretical lowest possible temperature at which all molecular motion ceases. Unlike Celsius or Fahrenheit, Kelvin does not use degrees and is the standard unit of temperature in the International System of Units (SI).

Measurements in Kelvin are crucial in scientific and engineering applications where precise temperature control and understanding of thermodynamic processes are essential. This includes fields like physics, chemistry, and atmospheric science. Converting between Kelvin and other temperature scales is straightforward. To convert from Celsius to Kelvin, simply add 273.15. For example, 0 degrees Celsius is equal to 273.15 K. Conversely, to convert from Kelvin to Celsius, subtract 273.15.

Instruments used for Kelvinmätning are typically calibrated to the Kelvin scale. These can range from simple thermometers in laboratory settings to sophisticated sensors used in industrial processes and space exploration. The accuracy of Kelvinmätning is vital for consistent and reproducible scientific results and for the proper functioning of many technological systems. Understanding Kelvinmätning is fundamental to comprehending many physical phenomena and engineering principles.
