How to Convert Kelvins to Fahrenheit

Thermometers measure temperature and come in many forms and sizes

Convert kelvins to degrees Fahrenheit with this simple formula:

degrees Fahrenheit = ( [K] - 273.15 ) × 9 / 5 + 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 Fahrenheit are both units used to measure temperature. Keep reading to learn more about each unit of measure.

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. 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.

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. 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.
