degree Kelvin [K] to degree Fahrenheit [F] Converter

Quick Reference

1 degree Kelvin (K) = -457.87 degree Fahrenheit (F)

1 degree Fahrenheit (F) = 255.9277778 degree Kelvin (K)

How to Convert degree Kelvin to degree Fahrenheit

1 K = -457.86999999999995 F
1 F = 255.92777777777775 K

To convert degree Kelvin to degree Fahrenheit, divide the value by 255.9277778 (equivalently, multiply by -457.87). To convert degree Fahrenheit back to degree Kelvin, multiply by 255.9277778.

Example: convert 10 K to F:
10 K = 10 x -457.86999999999995 = -4578.7 F

↔ Convert degree Fahrenheit to degree Kelvin

degree Kelvin

Definition: Degree Kelvin (K) is the base unit of temperature in the International System of Units (SI). It is an absolute thermodynamic temperature scale where 0 K is absolute zero, the point at which all molecular motion ceases.

History/origin: The Kelvin scale was proposed by William Thomson, 1st Baron Kelvin, in 1848. It is based on the Celsius scale, but with its zero point at absolute zero (-273.15 °C).

Current use: Degree Kelvin is primarily used in scientific and engineering applications where absolute temperature is required, such as thermodynamics, astrophysics, and low-temperature physics.

degree Fahrenheit

Definition: Degree Fahrenheit (°F) is a unit of temperature on the Fahrenheit scale, where the freezing point of water is 32 °F and the boiling point is 212 °F at standard atmospheric pressure.

History/origin: The Fahrenheit scale was developed in 1724 by the German physicist Daniel Gabriel Fahrenheit. He based his scale on the freezing point of a brine solution (0 °F) and the approximate body temperature of a human (96 °F, later adjusted to 98.6 °F).

Current use: Degree Fahrenheit is primarily used in the United States, its associated territories, and a few other countries for weather reporting and everyday temperature measurements.
