Fahrenheit and Kelvin

Fahrenheit and Kelvin are two different units used to measure temperature, each with its own zero point and scale.


The Fahrenheit scale, named after German physicist Daniel Gabriel Fahrenheit, is primarily used in the United States. On this scale, the freezing point of water is defined as 32 degrees Fahrenheit (°F), while the boiling point of water under standard atmospheric conditions is defined as 212 °F.


The Kelvin scale, named after Scottish physicist and engineer William Thomson, 1st Baron Kelvin, is the standard unit of temperature in the International System of Units (SI). It is an absolute temperature scale, which means that 0 Kelvin (symbol: K, without a degree sign) is defined as absolute zero, the theoretical point at which all molecular motion stops. On the Kelvin scale, the freezing point of water is 273.15 K and the boiling point is 373.15 K under standard atmospheric conditions.


To convert from Fahrenheit to Kelvin, first subtract 32 degrees from the Fahrenheit temperature, then multiply the result by 5/9, and finally add 273.15. The formula is

K = (°F - 32) * 5/9 + 273,15

To convert from Kelvin to Fahrenheit, first subtract 273.15 from the Kelvin temperature, then multiply the result by 9/5, and finally add 32. The formula is

°F = (K - 273,15) * 9/5 + 32
