Convert degrees Fahrenheit to Kelvin.

Fahrenheit °F to Kelvin K Formula

K equals °F plus 459.67, times 5/9.

K = (°F + 459.67) × 5/9

Alternatively, since multiplying by 5/9 is the same as dividing by 9/5 and 9/5 = 1.8 we can say K equals °F + 459.67, divided by 1.8.

K = (°F plus 459.67) / 1.8

How to Convert Fahrenheit to Kelvin

Add 459.67 to degrees Fahrenheit
Multiply the result by 5
Divide the result by 9

For example, to convert 82 degrees Fahrenheit to Kelvin, we plug our numbers into the formula as shown below:

K = (°F + 459.67) × 5/9

K = (82 + 459.67) × 5/9

K = 541.67 × 5 / 9

K = 2,708.35 / 9

K = 300.9278

82 degrees Fahrenheit is equal to about 301 Kelvin.

This calculator will show the steps to solve the °F to K formula so you know how make the conversion yourself.

Kelvin

Kelvin is a temperature scale and Kelvin are units of temperature on that scale. The symbol for Kelvin is K without a degree (°) symbol. On the Kelvin scale the boiling point of water is 373.15 K, the freezing point of water is 273.15 K and absolute zero is 0 K. The Kelvin scale does not contain negative values.

Fahrenheit

Fahrenheit is a temperature scale and degrees Fahrenheit are units of temperature on that scale. The symbol for degree Fahrenheit is °F. A temperature such as 72 °F is stated "seventy-two degrees Fahrenheit". On the Fahrenheit scale the boiling point of water is 212 °F, the freezing point of water is 32 °F and absolute zero is −459.67 °F.
