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.
Kelvin (K)
Definition: Kelvin (K) is the SI base unit of temperature, starting from absolute zero (0 K) where molecular motion stops. It is used in scientific and engineering fields.
History: The Kelvin scale was introduced by William Thomson (Lord Kelvin) in 1848, using absolute zero as the zero point and based on Celsius increments. It revolutionized thermodynamics and became the standard for scientific temperature measurements.
Current Use: Kelvin is essential in scientific research, particularly in physics, thermodynamics, and chemistry. It is used to express temperatures in absolute terms, crucial for understanding molecular behavior and energy systems.
