**Definitions:**

**Kelvin** (abbreviations: **K, or °K, or deg K**): is a unit of measure for temperature based upon an absolute scale, thermodynamic temperature scale using as its null point absolute zero, the temperature at which all thermal motion ceases in the classical description of thermodynamics. It was first proposed in 1848 and is one of the seven base units in the International System of Units (SI).

**Fahrenheit** (abbreviations: **F, or °F, or deg F**): is a temperature scale based on one proposed in 1724 by Amsterdam-based physicist Daniel Gabriel Fahrenheit (1686–1736), with regard to whom the scale is named.

## How to Convert Degree Kelvin to Degree Fahrenheit

*Example: How many degree Fahrenheit are equivalent to 20.77 degree Kelvin?*

As;

1 degree Kelvin = (1.8*X)-459.67 degree Fahrenheit

20.77 degree Kelvin = Y degree Fahrenheit

Assuming Y is the answer, and by substitution principle;

Y equals ( (1.8*20.77)-459.67 ) over 1, where X is substituted by 20.77

(i.e.) Y = ( (1.8*20.77)-459.67 ) / 1 = -422.284 degree Fahrenheit

Answer is: -422.284 degree Fahrenheit are equivalent to 20.77 degree Kelvin.
