## How to Convert Kelvins to Fahrenheit

Convert kelvins to degrees Fahrenheit with this simple formula:

The formula to convert kelvins to Fahrenheit is kelvins minus 273.15, times 9, divided by 5, plus 32. Insert the [K] temperature measurement in the formula and then solve to find the result.

**For example,** let's convert 50 K to degrees Fahrenheit:

50 K = ( ( 50 - 273.15 ) × 9 / 5 + 32 ) = -369.67 °F

Kelvins and the Fahrenheit scale are both used to measure temperature. Keep reading to learn more about each of them.

## Kelvins

The Kelvin scale is an absolute temperature scale that uses absolute zero as the starting point. The kelvin is defined in terms of the Boltzmann constant, which is a measure of the energy of motion corresponding to one kelvin.

More specifically, one kelvin is equal to the change of thermodynamic temperature that results in a change of thermal energy kT by 1.380649 × 10^{−23} J.^{[1]}

0 kelvins are equal to −273.15 degrees Celsius, which is the point of absolute zero.

The kelvin is the SI base unit for temperature in the metric system. Kelvins can be abbreviated as *K*, for example 1 kelvin can be written as 1 K.

The kelvin scale is different from other temperature scales in that it is not expressed in degrees, values are expressed in kelvins. When using the Kelvin scale in writing, the "k" is capitalized, however when using the kelvin as a unit the "k" should be lower-case, even though it is named for a person.

### Important Temperatures In Kelvins

Temperature | Kelvins |
---|---|

Absolute Zero | 0 K |

Freezing Point of Water | 273.15 K |

Triple Point of Water | 273.16 K |

Boiling Point of Water | 373.15 K |

## Fahrenheit

The Fahrenheit scale is a temperature scale that defines the melting point of water as 32 degrees and the boiling point of water at 212 degrees.^{[2]} There are 180 intervals between 32 °F and 212 °F, each corresponding to one degree.

The degree Fahrenheit is a US customary and imperial unit of temperature. Fahrenheit can be abbreviated as *F*, for example 1 degree Fahrenheit can be written as 1 °F.
