To convert Kelvin (K) to Fahrenheit (°F), use this formula:
Steps:
Quick example:
Tip: Kelvin has no degree sign. Write it as K, not °K.
Use this formula to convert Kelvin to Fahrenheit:
°F = (K − 273.15) × 9/5 + 32
Kelvin (K) is an absolute temperature scale. Fahrenheit (°F) is common in the United States.
This is the same as: °F = (K − 273.15) × 1.8 + 32.
0 K = -459.67 °F
This is absolute zero, the lowest possible temperature on the Kelvin scale.
273.15 K = 32 °F
273.15 K equals 0 °C, which is the freezing point of water at standard pressure.
300 K = 80.33 °F (rounded to two decimals)
Many science problems use 300 K as a simple room-temperature value.
310 K = 98.33 °F (rounded to two decimals)
310 K is close to normal human body temperature (about 98.6 °F).
373.15 K = 212 °F
This matches 100 °C, the boiling point of water at standard pressure.
Kelvin and Celsius have the same size degree, but different zero points.
0 °C equals 273.15 K, so you subtract 273.15 to shift from Kelvin to Celsius.
Yes. Kelvin values are never negative, but the Fahrenheit result can be negative.
Example: 200 K = -99.67 °F.
Negative Fahrenheit temperatures are common in cold weather and low-temperature science.
No. Write K, not °K.
Fahrenheit uses the degree symbol: °F.
Use this formula:
K = (°F − 32) × 5/9 + 273.15
This helps when you have a Fahrenheit temperature and need Kelvin for lab work or physics.
