0 K is equal to -459.67 Fahrenheit.
The conversion from Kelvin (K) to Fahrenheit (°F) involves first converting Kelvin to Celsius by subtracting 273.15, then converting Celsius to Fahrenheit by multiplying by 9/5 and adding 32. Since 0 K is absolute zero, it converts to -459.67 °F, the lowest possible temperature.

Conversion Formula
The formula to convert Kelvin (K) to Fahrenheit (°F) is:
°F = (K – 273.15) × 9/5 + 32
This works because Kelvin and Celsius scales differ by 273.15 degrees, so subtracting 273.15 converts Kelvin to Celsius. Then, since Fahrenheit is scaled differently, multiply Celsius by 9/5 and add 32 to get Fahrenheit.
For example, converting 0 K:
- 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
Conversion Example
- Convert 100 K to Fahrenheit:
- 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
- Convert 300 K to Fahrenheit:
- Subtract 273.15: 300 – 273.15 = 26.85 °C
- Multiply by 9/5: 26.85 × 9/5 = 48.33
- Add 32: 48.33 + 32 = 80.33 °F
- Convert 500 K to Fahrenheit:
- Subtract 273.15: 500 – 273.15 = 226.85 °C
- Multiply by 9/5: 226.85 × 9/5 = 408.33
- Add 32: 408.33 + 32 = 440.33 °F

Conversion Definitions
K (Kelvin): Kelvin is a temperature scale based on absolute zero, where 0 K is the lowest possible temperature and no thermal energy exists. It starts at absolute zero and increments in the same size units as Celsius but without negative values. It is widely used in science and engineering.
Fahrenheit: Fahrenheit is a temperature scale where water freezes at 32 °F and boils at 212 °F under standard atmosphere. It is mainly used in the United States for everyday temperature measurement. The scale is based on degrees that are smaller than Celsius.
Conversion FAQs
Can Kelvin values be negative, and what does that mean for Fahrenheit?
Negative Kelvin values don’t exist physically, since Kelvin starts at absolute zero (0 K). However, if negative numbers are entered, the formula still calculates Fahrenheit mathematically, but those temperatures are not physically meaningful. Actual temperatures below 0 K can’t happen.
Why is 0 Kelvin equal to -459.67 Fahrenheit and not a whole number?
The conversion involves constants and fractions that result in decimal values. Since Kelvin and Fahrenheit scales have different zero points and unit sizes, converting 0 K to Fahrenheit gives a decimal value (-459.67 °F), reflecting the precise equivalence of absolute zero on the Fahrenheit scale.
Does this conversion formula work for all Kelvin values?
Yes, the formula applies to any Kelvin value, positive or zero. Since Kelvin and Fahrenheit are absolute scales, the formula correctly converts temperatures within the physical range of Kelvin. Negative Kelvin values aren’t physically valid but can be converted mathematically.
Is the conversion affected by pressure or altitude?
No, temperature conversion between Kelvin and Fahrenheit is independent of pressure or altitude. These are purely scale conversions relating to temperature units, so environmental conditions don’t change the numerical conversion result.
How precise is the conversion when using decimal places?
The conversion is precise as long as the input value is accurate. Rounding to four decimal places like in the tool provides a good balance of precision for most uses. More decimals can be used if needed for scientific calculations, but four decimals are enough for general purposes.
