100 kelvin equals -279.67 degrees Fahrenheit.
To convert 100 kelvin to fahrenheit, you subtract 273.15 to get celsius, then convert that celsius value to fahrenheit by multiplying by 9/5 and adding 32. This two-step process converts the absolute temperature scale to the familiar fahrenheit scale.

Conversion Formula
The formula to convert kelvin to fahrenheit is:
F = (K – 273.15) × 9/5 + 32
It works because kelvin and celsius differ by 273.15 degrees, and fahrenheit relates to celsius by multiplying by 9/5 and adding 32. First, you convert kelvin to celsius by subtracting 273.15, then convert that celsius to fahrenheit.
For example, converting 100 K to °F:
- Subtract 273.15: 100 – 273.15 = -173.15 °C
- Multiply by 9/5: -173.15 × 9/5 = -311.67
- Add 32: -311.67 + 32 = -279.67 °F
So, 100 kelvin equals -279.67 fahrenheit.
Conversion Example
- Convert 200 K to °F:
- Subtract 273.15: 200 – 273.15 = -73.15 °C
- Multiply by 9/5: -73.15 × 9/5 = -131.67
- Add 32: -131.67 + 32 = -99.67 °F
- Convert 0 K to °F:
- Subtract 273.15: 0 – 273.15 = -273.15 °C
- Multiply by 9/5: -273.15 × 9/5 = -491.67
- Add 32: -491.67 + 32 = -459.67 °F
- Convert 310 K to °F:
- Subtract 273.15: 310 – 273.15 = 36.85 °C
- Multiply by 9/5: 36.85 × 9/5 = 66.33
- Add 32: 66.33 + 32 = 98.33 °F
- Convert 273 K to °F:
- Subtract 273.15: 273 – 273.15 = -0.15 °C
- Multiply by 9/5: -0.15 × 9/5 = -0.27
- Add 32: -0.27 + 32 = 31.73 °F

Conversion Definitions
Kelvin: Kelvin is an absolute temperature scale used in science where zero kelvin represents absolute zero, the lowest theoretical temperature. It uses the same increments as degrees celsius but starts at absolute zero, making it useful for thermodynamics and physics calculations.
Fahrenheit: Fahrenheit is a temperature scale mainly used in the United States, where water freezes at 32 °F and boils at 212 °F. It divides the range between freezing and boiling of water into 180 equal parts, commonly used for weather and everyday temperature measurements.
Conversion FAQs
Why do I subtract 273.15 when converting kelvin to fahrenheit?
You subtract 273.15 because kelvin and celsius scales have the same size degrees but different starting points. Kelvin starts at absolute zero, while celsius starts at the freezing point of water. Converting kelvin to celsius requires removing the offset of 273.15 before converting to fahrenheit.
Is kelvin used outside scientific fields?
Kelvin is mostly used in scientific and engineering fields where precise temperature measurements are needed. It is rare to use kelvin in everyday life or weather forecasts, where celsius or fahrenheit scales are preferred.
Can kelvin temperatures be negative?
No, kelvin cannot be negative because it starts at absolute zero, the lowest possible temperature. Negative values would imply a temperature colder than absolute zero, which is physically impossible.
How accurate is the conversion formula for kelvin to fahrenheit?
The formula F = (K – 273.15) × 9/5 + 32 is exact mathematically if you use precise constants. Any small inaccuracies come from rounding numbers or measurement errors, not the formula itself.
Does the conversion change at very high temperatures?
The conversion formula works for all temperatures within the physical range of kelvin. Even at extremely high temperatures, the relationship between kelvin, celsius, and fahrenheit remains linear and valid.
