Kelvin is a unit of measurement for temperature in the International System of Units (SI). It is named after the Scottish physicist William Thomson, 1st Baron Kelvin. The Kelvin scale is an absolute thermodynamic temperature scale, meaning it starts at absolute zero, the point at which all molecular motion ceases. This is equivalent to -273.15 degrees Celsius or -459.67 degrees Fahrenheit. The Kelvin scale is used primarily in scientific and engineering contexts, as it provides a more straightforward way to describe the behavior of gases and other substances under varying temperatures. Unlike the Celsius and Fahrenheit scales, the Kelvin scale does not use a degree symbol; temperatures are simply stated in Kelvins (K). For example, room temperature is approximately 293 K. The Kelvin scale is also used in the definition of the triple point of water, which is exactly 273.16 K. This definition is used to calibrate thermometers and other temperature-measuring devices.
