270 kelvin is equal to -9.67 degrees Fahrenheit.
To convert 270 kelvin to fahrenheit, we subtract 273.15 from the kelvin value to get celsius, then multiply by 9/5 and add 32 to get fahrenheit. This two-step method allows us to change the absolute temperature scale (kelvin) into the temperature scale commonly used in the US (fahrenheit).

Conversion Formula
The formula to convert kelvin (K) to fahrenheit (°F) is:
°F = (K – 273.15) × 9/5 + 32
This works by first converting kelvin to celsius by subtracting 273.15, because kelvin is an absolute scale starting at absolute zero, whereas celsius is based on water’s freezing point. Then, celsius is converted to fahrenheit by multiplying by 9/5 (the ratio of the temperature intervals) and adding 32 (the offset between freezing points).
Example for 270 K:
Step 1: 270 – 273.15 = -3.15 (°C)
Step 2: -3.15 × 9/5 = -5.67
Step 3: -5.67 + 32 = 26.33 (°F)
Wait, this seems off! Actually, the calculation corrects to:
(270 – 273.15) = -3.15
-3.15 × 9/5 = -5.67
-5.67 + 32 = 26.33°F? No, this is incorrect, something’s wrong.
Actually, the typical conversion uses the formula correctly, but the initial paragraph says -9.67°F for 270K, so let’s double-check:
270K – 273.15 = -3.15°C
-3.15 × 9/5 = -5.67°F
-5.67 + 32 = 26.33°F, so this is 26.33°F, but the initial answer was -9.67°F. So there is an inconsistency.
It seems earlier paragraph had error. Actually, the formula is correct, so 270K = 26.33°F, not -9.67°F.
Therefore, the initial result must be corrected to 26.33°F.
Corrected: 270 kelvin is equal to 26.33 degrees Fahrenheit.
Conversion Example
- Convert 280 K to °F:
- Subtract 273.15: 280 – 273.15 = 6.85 °C
- Multiply by 9/5: 6.85 × 9/5 = 12.33
- Add 32: 12.33 + 32 = 44.33 °F
- Convert 250 K to °F:
- 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 290 K to °F:
- Subtract 273.15: 290 – 273.15 = 16.85 °C
- Multiply by 9/5: 16.85 × 9/5 = 30.33
- Add 32: 30.33 + 32 = 62.33 °F
- Convert 260 K to °F:
- Subtract 273.15: 260 – 273.15 = -13.15 °C

Conversion Definitions
Kelvin: Kelvin is the base unit of temperature in the International System of Units (SI), used mainly in science. It starts from absolute zero, the lowest possible temperature where all molecular motion stops, and has no negative values. Each kelvin is the same size as one degree Celsius.
Fahrenheit: Fahrenheit is a temperature scale used in the United States and some Caribbean countries. It sets the freezing point of water at 32 degrees and boiling point at 212 degrees. The scale divides the range between freezing and boiling into 180 parts, making one degree Fahrenheit smaller than one degree Celsius.
Conversion FAQs
Why do we subtract 273.15 in the kelvin to fahrenheit conversion?
Kelvin is an absolute temperature scale beginning at absolute zero, which is 0 K. Celsius scale, however, sets 0°C at water’s freezing point. Since kelvin and celsius degree sizes are equal, subtracting 273.15 converts kelvin to celsius before converting to fahrenheit. This step aligns the zero points.
Can kelvin temperature be negative?
No, kelvin cannot be negative because it starts at absolute zero, the theoretical lowest temperature possible. Temperatures below 0 K do not exist within classical thermodynamics, so kelvin values are always 0 or positive.
Does the size of a kelvin degree equal a fahrenheit degree?
No, degrees kelvin and fahrenheit differ in size. One kelvin degree equals one celsius degree, but fahrenheit degrees are smaller. Specifically, 1 kelvin equals 1.8 (or 9/5) degrees Fahrenheit, so the scales differ both in zero points and degree sizes.
Is the conversion formula same for converting kelvin to celsius?
No, converting kelvin to celsius only requires subtracting 273.15, since both use the same degree size but different zero points. To get fahrenheit, additional steps of scaling and offset addition are needed.
Why does the conversion formula add 32 at the end?
The addition of 32 shifts the scale from celsius to fahrenheit because 0 °C corresponds to 32 °F. This offset adjusts the zero points between the two scales after scaling the degree size difference.
