Kelvin (K) - Definition and Overview

What is Kelvin?

The kelvin is the SI base unit of temperature. The symbol for kelvin is °K. Pure water freezes very close to 273.15 K and boils close to 373.15 K at standard atmospheric pressure.

Summary

  • The Kelvin scale is the base unit of 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 temperature scale starting at absolute zero, the theoretical point where all molecular motion ceases
  • The freezing point of water is 273.15 K and the boiling point is 373.15 K under standard atmospheric pressure
  • Unlike the Celsius and Fahrenheit scales, the Kelvin scale does not use the degree symbol (°) and is simply denoted as K.

Fahrenheit (°F) - Definition and Overview

What is Fahrenheit?

The Fahrenheit scale is a temperature scale based on one proposed in 1724 by the physicist Daniel Gabriel Fahrenheit. The unit symbol is °F. Fahrenheit scale was defined by two fixed points with a 180 °F separation: the temperature at which pure water freezes was defined as 32 °F and the boiling point of water was defined to be 212 °F, both at sea level and under standard atmospheric pressure.

Summary

  • The Fahrenheit scale is a temperature scale that was proposed by Daniel Gabriel Fahrenheit in 1724
  • It is used primarily in the United States and its territories, as well as some Caribbean nations
  • The scale is defined by two fixed points: the freezing point of water at 32 degrees Fahrenheit and the boiling point of water at 212 degrees Fahrenheit, both at standard atmospheric pressure
  • The Fahrenheit scale is based on a 180-degree separation between these two points, making it less intuitive than the Celsius scale for scientific purposes.
