How to use this Kelvin to Fahrenheit Converter 🤔

Follow these steps to convert given temperature from the units of Kelvin to the units of Fahrenheit.

1. Enter the input Kelvin value in the text field.
2. The calculator converts the given Kelvin into Fahrenheit in realtime ⌚ using the conversion formula, and displays under the Fahrenheit label. You do not need to click any button. If the input changes, Fahrenheit value is re-calculated, just like that.
3. You may copy the resulting Fahrenheit value using the Copy button.
4. To view a detailed step by step calculation of the conversion, click on the View Calculation button.
5. You can also reset the input by clicking on Reset button present below the input field.

What is the Formula to convert Kelvin to Fahrenheit?

The formula to convert given temperature from Kelvin to Fahrenheit is:

Temperature_(Fahrenheit) = Temperature_(Kelvin) × 9 / 5 - 459.67

Substitute the given value of temperature in kelvin, i.e., Temperature_(Kelvin) in the above formula and simplify the right-hand side value. The resulting value is the temperature in fahrenheit, i.e., Temperature_(Fahrenheit).

Calculation

Calculation will be done after you enter a valid input.

Examples

1

Consider that the operating temperature of a high-end processor is 320 Kelvin.
Convert this temperature from Kelvin to Fahrenheit.

Answer:

Given:

The temperature in kelvin is:

Temperature_(Kelvin) = 320

Formula:

The formula to convert temperature from kelvin to fahrenheit is:

Temperature_(Fahrenheit) = Temperature_(Kelvin) × 9 / 5 - 459.67

Substitution:

Substitute given weight Temperature_(Kelvin) = 320 in the above formula.

Temperature_(Fahrenheit) = 320 × 9 / 5 - 459.67

Temperature_(Fahrenheit) = 116.33

Final Answer:

Therefore, 320 K is equal to 116.33 °F.

The temperature is 116.33 °F, in fahrenheit.

2

Consider that the temperature of liquid nitrogen is approximately 77 Kelvin.
Convert this temperature from Kelvin to Fahrenheit.

Answer:

Given:

The temperature in kelvin is:

Temperature_(Kelvin) = 77

Formula:

The formula to convert temperature from kelvin to fahrenheit is:

Temperature_(Fahrenheit) = Temperature_(Kelvin) × 9 / 5 - 459.67

Substitution:

Substitute given weight Temperature_(Kelvin) = 77 in the above formula.

Temperature_(Fahrenheit) = 77 × 9 / 5 - 459.67

Temperature_(Fahrenheit) = -321.07

Final Answer:

Therefore, 77 K is equal to -321.07 °F.

The temperature is -321.07 °F, in fahrenheit.

Kelvin

The Kelvin scale is an absolute temperature scale named after the Scottish physicist William Thomson, 1st Baron Kelvin. It is commonly used in scientific and engineering applications where an absolute temperature reference is required. The Kelvin scale starts at absolute zero, the point at which all molecular motion ceases. The freezing point of water on the Kelvin scale is 273.15 K, and the boiling point is 373.15 K.

Fahrenheit

Fahrenheit is a temperature scale proposed by the German physicist Daniel Gabriel Fahrenheit. On the Fahrenheit scale, the freezing point of water is 32 degrees, and the boiling point is 212 degrees under standard atmospheric pressure. The Fahrenheit scale is commonly used in the United States and some other countries, especially for weather reporting and everyday temperature measurements.
