Kelvin to Fahrenheit

To convert Kelvin to Fahrenheit, we use the formula °F = (K − 273.15) × 9/5 + 32, in which we substitute the value of Kelvin to get the temperature in Fahrenheit. Kelvin and Fahrenheit are scales that are used to measure temperature. Let us learn more about the Kelvin to Fahrenheit formula and its conversion in this article.

Kelvin to Fahrenheit Formula

Kelvin and Fahrenheit are the two scales on which temperature is measured. Sometimes we need to convert the temperature from the Kelvin scale to the Fahrenheit scale in order to compare or add/subtract the temperatures. Kelvin is the SI unit of temperature. It is denoted by the symbol K. Note that Kelvin is an absolute scale and that is why we do not use the degree symbol with it. Fahrenheit is a unit for measuring temperature in which water freezes at 32° and boils at 212° under standard conditions. It is denoted by the letter F. Look at the image given below showing the boiling point and freezing point of water in Kelvin and Fahrenheit scales.

The Kelvin to Fahrenheit formula (also known as 'k to f formula') is given as °F = (K − 273.15) × 9/5 + 32 or °F = (K − 273.15) × 1.8 + 32. It is used to convert the temperature from Kelvin to Fahrenheit.

Look at the following example to get a better understanding.

Example: What is 300 Kelvin to Fahrenheit?

300 Kelvin is 80.33° F. To solve this, we need to put the value of K as 300 in the K to F formula given above.

⇒ °F = (300 − 273.15) × 1.8 + 32

⇒ °F = 26.85 × 1.8 + 32

⇒ °F = 48.33 + 32

⇒ °F = 80.33°

It is the easiest way to convert Kelvin to Fahrenheit. Another way of K to F conversion is to first convert Kelvin to Celsius and then Celsius to Fahrenheit. Now, let us learn the steps to convert K to F using the above K to F formula.

How to Convert Kelvin to Fahrenheit?

To convert Kelvin to Fahrenheit, we need to simply put the given value in the above k to f formula. The steps to convert k to f (Kelvin to Fahrenheit) are given below:

• Step 1: Put the given value (in K) in the formula: °F = (K − 273.15) × 1.8 + 32.
• Step 2: Simplify the expression and find the answer.
• Step 3: Write the final answer in °F.

Let us take an example of Kelvin to Fahrenheit (K to F) conversion. Convert 100 Kelvin to Fahrenheit. Let us apply the above formula, °F = (K − 273.15) × 1.8 + 32. Substitute the value of K with 100. We get °F = (100 − 273.15) × 1.8 + 32.

⇒ °F = (− 173.15) × 1.8 + 32

⇒ °F = - 311.67 + 32

⇒ °F = - 279.67

So, 100 Kelvin to Fahrenheit is - 279.67 °F.
