Kelvin: Kelvin (K) is the base unit of temperature in the International System of Units (SI) and is named after the Scottish physicist William Thomson, 1st Baron Kelvin. The Kelvin scale is an absolute thermodynamic temperature scale where 0 K, or absolute zero, is the point at which molecular motion ceases, representing the lowest possible temperature. The scale increments are equivalent to those of the Celsius scale, with each Kelvin unit corresponding to one degree Celsius. Kelvin is primarily used in scientific research, particularly in physics and chemistry, for precise measurements of temperature, including cryogenics, space science, and high-temperature processes. Unlike Celsius and Fahrenheit, the Kelvin scale does not use the term "degrees," and temperatures are simply expressed in Kelvins (e.g., 300 K).
Fahrenheit: Fahrenheit (°F) is a temperature scale developed by the German physicist Daniel Gabriel Fahrenheit in the early 18th century. In this scale, the freezing point of water is 32 degrees, and the boiling point is 212 degrees at standard atmospheric pressure. The Fahrenheit scale divides the interval between these two points into 180 equal parts. Although it is primarily used in the United States and its territories, the Fahrenheit scale is also used in some Caribbean countries for weather forecasts, as well as for measuring temperatures in household settings, including cooking and air conditioning.
