Fahrenheit to Kelvin Converter

The Fahrenheit to Kelvin Converter is a quick and reliable tool that helps users convert temperature from Fahrenheit (°F) to Kelvin (K) — the SI unit of temperature. Ideal for students, scientists, engineers, and travelers, this converter ensures accurate results in just seconds.

What is Fahrenheit to Kelvin Conversion?

The Kelvin scale starts at absolute zero and is widely used in scientific calculations and thermodynamic equations. To convert Fahrenheit to Kelvin, you need to use a two-step formula: Kelvin = (Fahrenheit − 32) × 5/9 + 273.15

Let’s convert 77°F to Kelvin:

Kelvin = (77 - 32) × 5/9 + 273.15
Kelvin = 45 × 5/9 + 273.15
Kelvin = 25 + 273.15 = 298.15 K

FAQ on Fahrenheit to Kelvin Converter

1. How do I convert Fahrenheit to Kelvin?

Use the formula: (°F − 32) × 5/9 + 273.15. Example: 98.6°F → (98.6 − 32) × 5/9 + 273.15 = 310.15 K

2. What is the freezing point in Fahrenheit and Kelvin?

Freezing point of water is 32°F or 273.15 K.

3. Is Kelvin ever negative?

No. The Kelvin scale starts at 0 K (absolute zero) and does not include negative values.

4. What is body temperature in Kelvin?

Normal body temperature (~98.6°F) is around 310.15 K.

5. Why use Kelvin instead of Celsius or Fahrenheit in science?

Kelvin is used in science because it starts at absolute zero, making it ideal for thermodynamic and molecular-level studies.

Did You Know?

Kelvin is the only temperature scale that does not use degrees — it’s simply Kelvin (K), not °K. It’s named after Lord Kelvin, who developed the concept of absolute temperature. In space and cryogenics, temperature is almost always measured in Kelvin!
