The conversion of 0°F to Kelvin results in 255.3722 K.
To convert Fahrenheit to Kelvin, first subtract 32 from the Fahrenheit temperature, then multiply the result by 5/9, and finally add 273.15 to convert to Kelvin. For 0°F, subtracting 32 gives -32, which when multiplied by 5/9 equals approximately -17.78. Adding 273.15 results in about 255.37 Kelvin.

Conversion Formula
The formula to convert Fahrenheit to Kelvin is (F – 32) * 5/9 + 273.15. This works because Fahrenheit and Kelvin scales are both linear, but they start at different points. Subtracting 32 adjusts for the Fahrenheit offset, multiplying by 5/9 converts the units, and adding 273.15 shifts to Kelvin.
For example, if F=0, then (0 – 32) * 5/9 + 273.15 equals (-32) * 5/9 + 273.15, which calculates as -17.78 + 273.15 = 255.37 K.
Conversion Example
- Convert 32°F to Kelvin:
- Subtract 32: 32 – 32 = 0
- Multiply by 5/9: 0 * 5/9 = 0
- Add 273.15: 0 + 273.15 = 273.15 K
- Convert -40°F to Kelvin:
- Subtract 32: -40 – 32 = -72
- Multiply by 5/9: -72 * 5/9 ≈ -40
- Add 273.15: -40 + 273.15 ≈ 233.15 K
- Convert 100°F to Kelvin:
- Subtract 32: 100 – 32 = 68
- Multiply by 5/9: 68 * 5/9 ≈ 37.78
- Add 273.15: 37.78 + 273.15 ≈ 310.93 K
- Convert -10°F to Kelvin:
- Subtract 32: -10 – 32 = -42
- Multiply by 5/9: -42 * 5/9 ≈ -23.33
- Add 273.15: -23.33 + 273.15 ≈ 249.82 K

Conversion Definitions
f
Fahrenheit (f) is a temperature scale where 32°F is freezing point of water and 212°F is boiling point, based on 180 divisions. It is mainly used in the United States, and its units measure temperature differences, not absolute temperature.
kelvin
Kelvin (K) is the SI base unit for temperature, starting at absolute zero, the point where particles have minimum thermal motion. It is used in science for precise temperature measurements, with each kelvin equal to one degree Celsius.
Conversion FAQs
Why does subtracting 32 from Fahrenheit work for conversion?
Subtracting 32 adjusts for the offset in the Fahrenheit scale, which starts at 32°F for water freezing. This aligns the scale with Celsius and Kelvin, allowing for proper conversion of temperatures, especially when shifting from Fahrenheit’s arbitrary zero point.
Why do we add 273.15 after the calculation?
Adding 273.15 shifts the temperature from Celsius to Kelvin, because Kelvin starts at absolute zero, which is -273.15°C. This ensures the final temperature reflects the true thermodynamic temperature in Kelvin scale.
Can I convert Fahrenheit to Kelvin without a calculator?
Yes, using approximation formulas or reference tables can help, but for precise results, especially with decimal points, calculator or digital tools are recommended. The formula (F – 32) * 5/9 + 273.15 provides accurate conversion.
