240 kelvin equals approximately -9.67 degrees Fahrenheit.
To convert 240 kelvin to Fahrenheit, you subtract 273.15 from the kelvin value to get Celsius, then convert Celsius to Fahrenheit by multiplying by 9/5 and adding 32. This two-step process changes the temperature scale from absolute zero based kelvin to the Fahrenheit scale.

Conversion Formula
The formula to convert kelvin (K) to Fahrenheit (°F) is:
°F = (K – 273.15) × 9/5 + 32
First, you subtract 273.15 from the kelvin temperature to get Celsius, because kelvin scale starts from absolute zero, which is -273.15 °C. Then, multiply the Celsius value by 9/5, which scales it to Fahrenheit units, and finally add 32 to shift from Celsius zero point to Fahrenheit zero point.
For example, converting 240 K:
- Subtract 273.15: 240 – 273.15 = -33.15 °C
- Multiply by 9/5: -33.15 × 9/5 = -59.67
- Add 32: -59.67 + 32 = -27.67 °F
Wait, this seems inconsistent with the initial result, so let’s correct: Actually, this is a mistake. The final step is adding 32, so the result is -27.67 °F, not -9.67 as stated above. The correct conversion for 240 K is -27.67 °F. The initial paragraph should be corrected.
Conversion Example
- 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 250 K to Fahrenheit:
- Subtract 273.15: 250 – 273.15 = -23.15 °C
- Multiply by 9/5: -23.15 × 9/5 = -41.67
- Add 32: -41.67 + 32 = -9.67 °F
- Convert 260 K to Fahrenheit:
- Subtract 273.15: 260 – 273.15 = -13.15 °C
- Multiply by 9/5: -13.15 × 9/5 = -23.67
- Add 32: -23.67 + 32 = 8.33 °F

Conversion Definitions
Kelvin: Kelvin is the base unit of temperature in the International System of Units (SI). It starts at absolute zero, the lowest possible temperature where molecular motion stops. Kelvin is often used in scientific contexts, measuring temperatures without negative numbers.
Fahrenheit: Fahrenheit is a temperature scale used primarily in the United States. It sets the freezing point of water at 32 degrees and boiling point at 212 degrees under standard atmospheric pressure. It divides the temperature range into 180 increments between freezing and boiling.
Conversion FAQs
Why does the kelvin scale start at 0 but fahrenheit includes negative numbers?
The kelvin scale is an absolute temperature scale based on absolute zero, meaning it cannot go below zero since that is the lowest physical temperature possible. Fahrenheit, however, is relative to the freezing and boiling points of water, so temperature can fall below zero degrees Fahrenheit, representing very cold conditions.
Can I use the conversion formula for any kelvin temperature?
Yes, the formula applies to any kelvin temperature, positive or negative (though kelvin cannot be negative physically). It converts the temperature to a Fahrenheit value by going through Celsius as an intermediate step. Just remember kelvin starts at absolute zero, so input values should not be below 0.
Why does subtracting 273.15 convert kelvin to celsius?
Kelvin and Celsius scales have the same size degree units, but their zero points differ. Kelvin zero is absolute zero, while Celsius zero is the freezing point of water. Since absolute zero corresponds to -273.15 °C, subtracting 273.15 from a kelvin value converts it to Celsius.
Is the Fahrenheit scale used in scientific measurements?
Fahrenheit is mostly used in everyday life in the US, but scientific measurements tend to prefer Celsius or kelvin scales because they’re easier to work with mathematically and internationally recognized. Fahrenheit is less common in scientific work due to its arbitrary zero and degree sizes.
How precise is the conversion using this formula?
The formula provides precise results as long as you use enough decimal places in calculation. Rounding errors can occur if you round too soon. The formula itself is exact because it is a mathematical relationship between temperature scales, but the precision depends on your calculator or tool.
