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.

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).

How to Convert Degree Fahrenheit to Degree Kelvin

Example: How many degree Kelvin are equivalent to 31.57 degree Fahrenheit?


1 degree Fahrenheit = (5/9)*(X+459.67) degree Kelvin

31.57 degree Fahrenheit = Y degree Kelvin

Assuming Y is the answer, and by substitution principle;

Y equals ( (5/9)*(31.57+459.67) ) over 1, where X is substituted by 31.57

(i.e.) Y = ( (5/9)*(31.57+459.67) ) / 1 = 272.91111111111 degree Kelvin

Answer is: 272.91111111111 degree Kelvin are equivalent to 31.57 degree Fahrenheit.
