- Scientific temperature measurement
Organizing and summarizing search results for youKelvin is a unit of temperature in the International System of Units (SI). It is an absolute temperature scale that begins at absolute zero, where all thermal motion ceases. The Kelvin scale is recognized as the international standard for scientific temperature measurement. It is commonly used in scientific research and measurements.5 Sources - See more
