Kelvinasteikkona

Kelvinasteikkona, also known as the Kelvin scale, is a thermodynamic temperature scale where absolute zero, the theoretical point at which all thermal motion ceases, is assigned a value of 0. The scale is named after Lord Kelvin, who first proposed it in 1848. The Kelvin scale is part of the International System of Units (SI) and is used primarily for scientific purposes. Unlike the Celsius and Fahrenheit scales, the Kelvin scale does not use degrees; it is simply referred to as "kelvins." The Kelvin scale is an absolute scale, meaning it starts at absolute zero, which is equivalent to -273.15 degrees Celsius or -459.67 degrees Fahrenheit. The Kelvin scale is used in many scientific and engineering applications, including physics, chemistry, and materials science, where absolute temperature measurements are crucial. It is also used in the study of thermodynamics and statistical mechanics. The Kelvin scale is widely used in scientific literature and is the standard temperature scale for many international and national standards organizations.
