Conversion Formula
The formula to convert Fahrenheit (f) to kelvin (kalvin) is:
Kelvin = (Fahrenheit – 32) × 5/9 + 273.15
This formula works because Fahrenheit and Celsius scales differ by an offset and scale factor. First, subtract 32 from the Fahrenheit value to remove the offset, then multiply by 5/9 to convert to Celsius degrees. Finally, add 273.15 to convert Celsius to kelvin, which is the absolute temperature scale starting at absolute zero.
For example, converting 0 °F:
- Subtract 32: 0 – 32 = -32
- Multiply by 5/9: -32 × 5/9 = -17.7778 °C
- Add 273.15: -17.7778 + 273.15 = 255.3722 K
Conversion Example
- Convert 50 °F to kelvin:
- 50 – 32 = 18
- 18 × 5/9 = 10 °C
- 10 + 273.15 = 283.15 K
- Convert -40 °F to kelvin:
- -40 – 32 = -72
- -72 × 5/9 = -40 °C
- -40 + 273.15 = 233.15 K
- Convert 100 °F to kelvin:
- 100 – 32 = 68
- 68 × 5/9 ≈ 37.7778 °C
- 37.7778 + 273.15 ≈ 310.9278 K
- Convert 32 °F to kelvin:
- 32 – 32 = 0
- 0 × 5/9 = 0 °C
- 0 + 273.15 = 273.15 K

Conversion Definitions
f: Fahrenheit (f) is a temperature scale where water freezes at 32 degrees and boils at 212 degrees under standard atmospheric conditions. It uses degrees Fahrenheit (°F) as units, mostly used in the United States and few other countries for weather, cooking, and industrial measurements.
kalvin: Kelvin (kalvin) is an absolute temperature scale starting at absolute zero, the theoretical lowest temperature possible. It measures temperature in kelvins (K), widely used in science and engineering to describe thermodynamic temperature without negative values, unlike Celsius or Fahrenheit.
Conversion FAQs
Why do we need to subtract 32 in the Fahrenheit to kelvin conversion?
Subtracting 32 adjusts the Fahrenheit scale to align with the Celsius scale, since Fahrenheit sets the freezing point of water at 32 °F, while Celsius sets it at 0 °C. This step removes the offset before converting the scale factor and adding the kelvin offset.
Can I convert Fahrenheit directly to kelvin without Celsius?
The formula effectively converts Fahrenheit to kelvin in one step, but conceptually it passes through Celsius as an intermediary. The subtraction and multiplication correspond to converting to Celsius, then adding 273.15 shifts to kelvin.
Is kelvin just Celsius plus 273.15?
Yes, kelvin and Celsius scales have the same increment size, so kelvin equals Celsius temperature plus 273.15. Kelvin starts at absolute zero, so zero kelvin is -273.15 °C.
Why does 0 °F correspond to about 255 kelvin?
Because 0 °F is below the freezing point of water, converting it to kelvin involves first lowering it to negative Celsius and then shifting to kelvin scale. The calculation leads to approximately 255.37 kelvin, which is cold but above absolute zero.
Are there negative values in kelvin?
No, kelvin is an absolute scale beginning at absolute zero, so it has no negative values. Any temperature below 0 K is physically impossible. This is why the conversion ensures kelvin remains positive even for negative Fahrenheit values.
