Unit definitions
What is a kelvin?
The kelvin is the SI base unit of thermodynamic temperature, redefined in 2019 via the Boltzmann constant. Its zero point is absolute zero, the coldest possible temperature, and it uses the same degree size as Celsius. It is standard in science and engineering.
What is a degree Fahrenheit?
The degree Fahrenheit is the customary temperature unit in the United States, with water freezing at 32 °F and boiling at 212 °F. Each Fahrenheit degree is 5/9 of a kelvin, so the scale is finer than Celsius. Normal human body temperature is about 98.6 °F.
Frequently asked questions
What is the formula to convert kelvins to degrees Fahrenheit?
°F = (K − 273.15) × 9/5 + 32. For example, 20 K equals -423.67 °F.
What is 0 K in degrees Fahrenheit?
0 K equals -459.67 °F.
