Conversion Formula
The formula to convert Fahrenheit to Kelvin is:
K = (°F – 32) × 5/9 + 273.15
This formula first subtracts 32 from the Fahrenheit value to offset the freezing point difference between Fahrenheit and Celsius scales. Then, multiply by 5/9 to convert the scaled value to Celsius. Finally, add 273.15 to shift from Celsius to Kelvin, because Kelvin starts at absolute zero.
Example calculation for 61°F:
- Subtract 32 from 61: 61 – 32 = 29
- Multiply 29 by 5/9: 29 × 5/9 ≈ 16.1111
- Add 273.15 to 16.1111: 16.1111 + 273.15 = 289.2611 K
The result is approximately 289.26 kelvin.
Conversion Example
- Convert 45°F to Kelvin:
- Subtract 32: 45 – 32 = 13
- Multiply by 5/9: 13 × 5/9 ≈ 7.2222
- Add 273.15: 7.2222 + 273.15 = 280.3722 K
- Convert 100°F to Kelvin:
- Subtract 32: 100 – 32 = 68
- Multiply by 5/9: 68 × 5/9 ≈ 37.7778
- Add 273.15: 37.7778 + 273.15 = 310.9278 K
- Convert 0°F to Kelvin:
- Subtract 32: 0 – 32 = -32
- Multiply by 5/9: -32 × 5/9 ≈ -17.7778
- Add 273.15: -17.7778 + 273.15 = 255.3722 K

Conversion Definitions
Fahrenheit: Fahrenheit is a temperature scale where water freezes at 32 degrees and boils at 212 degrees at standard atmospheric pressure. It is mostly used in the United States, and some Caribbean countries. The scale was created by Daniel Gabriel Fahrenheit in the early 18th century.
Kelvin: Kelvin is the SI unit for temperature, based on absolute zero where all molecular motion stops. It starts at 0 K, which equals -273.15°C, and has the same increment size as Celsius. Kelvin is widely used in scientific measurements and physics.
Conversion FAQs
Can I convert Fahrenheit to Kelvin without converting to Celsius first?
While the formula includes a step that looks like converting Fahrenheit to Celsius, the entire formula K = (°F - 32) × 5/9 + 273.15 directly converts Fahrenheit to Kelvin in one calculation. So, no separate Celsius conversion is required if you apply this formula.
Why do I add 273.15 when converting to Kelvin?
The Kelvin scale starts at absolute zero, which is −273.15°C. Adding 273.15 shifts the Celsius temperature to Kelvin. Without this offset, the temperature would be relative to the Celsius zero point instead of absolute zero, which is fundamental in thermodynamics.
Is the Kelvin scale used for everyday temperature readings?
Kelvin is primarily used in scientific contexts, not for everyday weather or cooking temperatures. People use Celsius or Fahrenheit for daily life, while Kelvin measures temperatures in physics, chemistry, and engineering where absolute temperature matters.
Does converting Fahrenheit to Kelvin lose any precision?
Conversions can introduce small rounding errors, especially when decimals are involved. Using more decimal places reduces this, but the formula itself is precise. The precision mostly depends on how many decimal places you round the final answer to.
What is the freezing point of water in Kelvin?
The freezing point of water is 0°C, which is 273.15 K. This is found by converting 32°F to Kelvin or simply adding 273.15 to the Celsius freezing point. This value is a standard reference in temperature conversions.
