1 kelvin equals approximately -457.87 degrees Fahrenheit.
To convert 1 kelvin to fahrenheit, you subtract 273.15 to get Celsius, then convert Celsius to Fahrenheit with the formula (C × 9/5) + 32. So, 1 K is (1 – 273.15) = -272.15°C, then (-272.15 × 9/5) + 32 = -457.87°F.

Conversion Formula
The formula to convert kelvin to fahrenheit is based on two steps. First, subtract 273.15 from the kelvin value to get Celsius. Then, multiply Celsius by 9/5 and add 32 to find Fahrenheit. This method works because Celsius and Fahrenheit are linear scales, and Kelvin is just Celsius shifted by 273.15.
For example, if you have 300K, subtract 273.15 to get 26.85°C. Then, multiply 26.85 by 9/5 (which is 1.8), resulting in 48.33. Add 32 to get 80.33°F. This step-by-step approach ensures precise conversion between the scales.
Conversion Example
- Convert 5 kelvin:
- Subtract 273.15: 5 – 273.15 = -268.15°C
- Multiply by 9/5: -268.15 × 1.8 = -482.67
- Add 32: -482.67 + 32 = -450.67°F
- Convert 10 kelvin:
- Subtract 273.15: 10 – 273.15 = -263.15°C
- Multiply by 1.8: -263.15 × 1.8 = -473.67
- Add 32: -473.67 + 32 = -441.67°F
- Convert 25 kelvin:
- Subtract 273.15: 25 – 273.15 = -248.15°C
- Multiply by 1.8: -248.15 × 1.8 = -446.67
- Add 32: -446.67 + 32 = -414.67°F
- Convert 100 kelvin:
- Subtract 273.15: 100 – 273.15 = -173.15°C
- Multiply by 1.8: -173.15 × 1.8 = -311.67
- Add 32: -311.67 + 32 = -279.67°F
- Convert 0 kelvin:
- Subtract 273.15: 0 – 273.15 = -273.15°C
- Multiply by 1.8: -273.15 × 1.8 = -491.67
- Add 32: -491.67 + 32 = -459.67°F

Conversion Definitions
Kelvin
Kelvin is a temperature scale starting at absolute zero, the lowest possible temperature where particles have minimal motion. It is used mainly in scientific contexts and measures temperature without degrees, with each kelvin equivalent to one Celsius degree.
Fahrenheit
Fahrenheit is a temperature scale primarily used in the United States. It sets freezing point of water at 32°F and boiling point at 212°F under standard conditions. It uses 180 degrees between these points, making it different from Celsius and Kelvin.
Conversion FAQs
Why is Kelvin used in scientific measurements instead of Fahrenheit?
Kelvin is used in science because it starts at absolute zero, providing a true zero point, and allows for straightforward calculations of thermodynamic properties. Fahrenheit’s scale is less suited for scientific work due to its arbitrary zero point.
Can I convert Kelvin to Fahrenheit directly without intermediate steps?
Yes, by using the formula (K – 273.15) × 9/5 + 32, you can convert kelvin directly to fahrenheit. This method simplifies calculations when precise results are needed without converting through Celsius.
What is the significance of absolute zero in Kelvin scale?
Absolute zero, 0 kelvin, is the temperature where particles reach their minimum thermal motion, representing the lowest possible temperature. It is fundamental in thermodynamics and sets the zero point for the Kelvin scale.
How does the Kelvin scale help in temperature conversions?
Kelvin’s linear scale makes it easier to convert between temperature units because it is directly related to Celsius. The constant offset of 273.15 simplifies calculations, especially in scientific formulas and equations.
