Fahrenheit (°F)
Definition: Fahrenheit (°F) is a temperature scale where water freezes at 32°F and boils at 212°F under standard atmospheric conditions. It is mainly used in the United States.
History: The Fahrenheit scale was developed by Daniel Gabriel Fahrenheit in 1724, based on a brine freezing point, human body temperature, and water's freezing and boiling points. It became popular in English-speaking countries.
Current Use: Fahrenheit is primarily used in the US for weather, cooking, and industrial purposes. Despite global metrication, it remains prevalent in the US for daily temperature measurements.
Rankine (°R)
Definition: Rankine (°R) is a thermodynamic temperature scale that starts at absolute zero, using Fahrenheit increments. It is used in thermodynamics, particularly in the US.
History: The Rankine scale was developed by William John Macquorn Rankine in the 1850s, inspired by Kelvin but with Fahrenheit degrees. It was designed for thermodynamic calculations in systems using the Fahrenheit scale.
Current Use: Rankine is primarily used in thermodynamics in the US, especially in analyzing heat engines, refrigeration cycles, and energy systems. It is more specialized and less common than other temperature scales.
