Convert Fahrenheit to Kelvin, Calculator

Converting Fahrenheit degrees to Kelvin is done using a simple formula, i.e., (T)K = 5/9 (T)F + 459.67. Fahrenheit and Kelvin are two well-known and widely used temperature scales. While the Fahrenheit scale is used in the United States, the Kelvin scale is widely used for scientific calculations worldwide. There is much scientific and engineering equipment that uses the Fahrenheit scale. Let's look at how to derive the Fahrenheit to Kelvin formula with a few solved examples.

Fahrenheit and Kelvin are units of temperature measurement represented in Fahrenheit degrees and Kelvin, respectively. The Fahrenheit scale consists of smaller units, where a change of one degree on the Kelvin scale is equivalent to a change of 1.8°F on the Fahrenheit scale. To convert F to K, we need to use a simple formula that helps get the measurement. Temperature can be converted from Fahrenheit to Kelvin and vice versa. There are two ways to convert: direct conversion to Kelvin degrees or conversion to Celsius degrees first, followed by converting that measurement to Kelvin degrees.

Definition of Fahrenheit

Fahrenheit is a temperature scale based on 32° and 212° for the freezing and boiling points of water, respectively, with the interval between them divided into 180 equal parts. It is represented as °F and can also be used to convert a given temperature from Fahrenheit to other units of measurement.

Definition of Kelvin

Kelvin is the base unit of temperature measurement in the International System of Units. A fraction of 1/273.16 of the thermodynamic temperature represents the triple point of water, and this scale is known as Kelvin. It divides the interval between the ice and steam points into 100 divisions, making one Kelvin equivalent to one Celsius degree. This unit is represented as K without the degree symbol (°), as it is an absolute scale based on absolute zero.

Converting Fahrenheit to Kelvin is very simple. For reporting the temperature on the Kelvin scale, the degree symbol is not used; instead, they are denoted or marked as Kelvin. The Fahrenheit to Kelvin formula for a given temperature can be expressed as:

(T)_K = 5/9 [(T)_F + 459.67]

where,

• (T)_K = Temperature in Kelvin.

• (T)_F = Temperature in Fahrenheit.

Method 2: Convert Fahrenheit to Kelvin

In addition to using the aforementioned formula, we can also convert F to K using another method by following these simple steps:

• Subtract 32 from the Fahrenheit temperature.
• Multiply this number by 5.
• Divide this number by 9.
• Add 273.15 to this number.
