How to Convert Kelvin to Fahrenheit (K to °F)?

The conversion from Kelvin to Fahrenheit is straightforward: one Kelvin equals a Fahrenheit degree minus 273.15, multiplied by 9/5, and then adding 32. Therefore, to perform the conversion, simply subtract 273.15 from the Kelvin value, multiply the result by 9/5, and add 32.

Formula

This formula represents the conversion from Kelvin to Fahrenheit by subtracting 273.15 from the Kelvin value, then multiplying the result by 9/5, and finally adding 32.
Fahrenheit=(Kelvin−273.15)×95+32\text{Fahrenheit} = (\text{Kelvin} - 273.15) \times \frac{9}{5} + 32

Conversion Example: Kelvin to Fahrenheit

With these steps, you can easily convert Kelvin to Fahrenheit without the need for a calculator. Below, we provide practical examples to better understand the process.

Example 1

Convert 300 Kelvin to Fahrenheit.

This example shows how to convert 300 Kelvin to Fahrenheit. First, subtract 273.15 from 300, obtaining 26.85. Then, multiply this result by 9/5, obtaining 48.33. Finally, add 32, which results in 80.33 degrees Fahrenheit.
Fahrenheit=(300−273.15)×95+32=80.33 °F\text{Fahrenheit} = (300 - 273.15) \times \frac{9}{5} + 32 = 80.33\,\text{°F}

Result: 300 Kelvin equals 80.33 degrees Fahrenheit.

Example 2

Convert 250 Kelvin to Fahrenheit.

This example shows how to convert 250 Kelvin to Fahrenheit. First, subtract 273.15 from 250, obtaining -23.15. Then, multiply this result by 9/5, obtaining -41.67. Finally, add 32, which results in -9.67 degrees Fahrenheit.
Fahrenheit=(250−273.15)×95+32=−9.67 °F\text{Fahrenheit} = (250 - 273.15) \times \frac{9}{5} + 32 = -9.67\,\text{°F}

Result: 250 Kelvin equals -9.67 degrees Fahrenheit.

Frequently Asked Questions

How to convert Kelvin to Fahrenheit?

The formula to convert Kelvin (K) to Fahrenheit (F) is: F = (K - 273.15) × (9/5) + 32. First, subtract 273.15 to convert from Kelvin to Celsius, then multiply by 9/5, and finally add 32 to get the result in Fahrenheit.

What are some common Kelvin to Fahrenheit equivalents?

  • 0 K = -459.67 °F (absolute zero)
  • 273.15 K = 32 °F (freezing point of water)
  • 373.15 K = 212 °F (boiling point of water)
  • 298.15 K = 77 °F (typical room temperature)

What is absolute zero in Fahrenheit?

Absolute zero is the lowest possible temperature, where particles have the least possible thermal energy. On the Fahrenheit scale, it corresponds to -459.67 °F.

What are the main differences between Kelvin and Fahrenheit?

  • Kelvin: An absolute scale mainly used in science, based on absolute zero (0 K).
  • Fahrenheit: A relative scale primarily used in the United States, where 32 °F is the freezing point of water.
