0 °F is equal to approximately 255.3722 kelvin.
To convert 0 degrees Fahrenheit to kelvin, first convert Fahrenheit to Celsius, then Celsius to kelvin by adding 273.15. This two-step process accounts for differences in scale and zero points between the units.

Conversion Formula
To convert Fahrenheit (f) to kelvin (K), first subtract 32 from the Fahrenheit value, then multiply the result by 5/9 to convert to Celsius. After that, add 273.15 to convert Celsius to kelvin.
This formula works because Fahrenheit and Celsius scales have different zero points and increments, and kelvin starts from absolute zero, which is -273.15°C.
Step-by-step example for 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
Here are conversions for different Fahrenheit values, showing each step:
- 32 °F
- 32 – 32 = 0
- 0 × 5/9 = 0 °C
- 0 + 273.15 = 273.15 K
- 100 °F
- 100 – 32 = 68
- 68 × 5/9 ≈ 37.7778 °C
- 37.7778 + 273.15 ≈ 310.9278 K
- -40 °F
- -40 – 32 = -72
- -72 × 5/9 = -40 °C
- -40 + 273.15 = 233.15 K
- 212 °F
- 212 – 32 = 180
- 180 × 5/9 = 100 °C
- 100 + 273.15 = 373.15 K

Conversion Definitions
f: Fahrenheit is a temperature scale used primarily in the United States. Its zero point was originally based on a brine solution, and water freezes at 32 °F and boils at 212 °F. The scale divides the interval between freezing and boiling of water into 180 increments called degrees.
kalvin: Kelvin is the base unit of temperature in the International System of Units (SI). It starts at absolute zero, the coldest possible temperature where particles have minimal motion. Kelvin scale increments are same size as Celsius degrees, but zero kelvin is -273.15 °C.
Conversion FAQs
Why do we add 273.15 when converting Celsius to kelvin?
Adding 273.15 shifts the Celsius scale to absolute zero, which is 0 K. Since Celsius zero is at the freezing point of water, and kelvin zero is absolute zero, the addition aligns the scales correctly.
Can the conversion formula be simplified into one step?
Yes, the formula can be combined: K = (F – 32) × 5/9 + 273.15. This single formula converts Fahrenheit directly to kelvin without intermediate steps.
Does kelvin use degrees like Fahrenheit or Celsius?
No, kelvin is an absolute temperature scale and does not use “degrees.” It’s written as kelvin (K), not degrees kelvin.
What happens if the Fahrenheit value is negative?
Negative Fahrenheit values convert normally using the formula, often resulting in kelvin values above zero, since kelvin cannot be negative.
Is 0 °F considered cold in kelvin terms?
Yes, because 0 °F equals about 255 K, which is much colder than room temperature and below freezing point of water in kelvin (273.15 K).
