The Kelvin scale is an absolute temperature scale named after the Scottish physicist William Thomson, 1st Baron Kelvin. It is commonly used in scientific and engineering applications where an absolute temperature reference is required. The Kelvin scale starts at absolute zero, the point at which all molecular motion ceases. The freezing point of water on the Kelvin scale is 273.15 K, and the boiling point is 373.15 K.


Fahrenheit is a temperature scale proposed by the German physicist Daniel Gabriel Fahrenheit. On the Fahrenheit scale, the freezing point of water is 32 degrees, and the boiling point is 212 degrees under standard atmospheric pressure. The Fahrenheit scale is commonly used in the United States and some other countries, especially for weather reporting and everyday temperature measurements.
