Kelvin to Fahrenheit Converter
📚 Examples, Formula, and How To
📝 Kelvin to Fahrenheit Formula
Kelvin to Fahrenheit
°F = (K - 273.15) × 9/5 + 32To convert Kelvin to Fahrenheit, subtract 273.15, multiply by 9/5, then add 32. This accounts for both the different zero points and scale differences.
Fahrenheit to Kelvin
K = (°F - 32) × 5/9 + 273.15To convert Fahrenheit to Kelvin, subtract 32, multiply by 5/9, then add 273.15. This is the inverse of the Kelvin to Fahrenheit conversion.
💡 Converting Kelvin to Fahrenheit
Example 1
Convert: 273.15 K to Fahrenheit
Start with the conversion formula: °F = (K - 273.15) × 9/5 + 32
Substitute the value: °F = (273.15 - 273.15) × 9/5 + 32
Calculate: °F = 0 × 9/5 + 32 = 32
Example 2
Convert: 373.15 K to Fahrenheit
Start with the conversion formula: °F = (K - 273.15) × 9/5 + 32
Substitute the value: °F = (373.15 - 273.15) × 9/5 + 32
Calculate: °F = 100 × 9/5 + 32 = 180 + 32 = 212
Example 3
Convert: 310.15 K to Fahrenheit
Start with the conversion formula: °F = (K - 273.15) × 9/5 + 32
Substitute the value: °F = (310.15 - 273.15) × 9/5 + 32
Calculate: °F = 37 × 9/5 + 32 = 66.6 + 32 = 98.6

📚 What are Kelvin and Fahrenheit?
📏 Kelvin(K)
Definition:
Kelvin is the base unit of temperature in the International System of Units (SI). It starts at absolute zero and uses the same scale intervals as Celsius.
History:
Named after Lord Kelvin (William Thomson) in 1848. It's based on absolute zero, the theoretical temperature where all molecular motion ceases.
Common Uses:
- Scientific research and calculations
- Physics and chemistry laboratories
- Astronomy and space science
- Engineering thermodynamics
- International scientific standards
Fun Fact:
Kelvin is the only temperature scale that doesn't use degree symbols - we say '300 K', not '300°K'! Absolute zero (0 K) is the coldest possible temperature in the universe.
📏 Fahrenheit(°F)
Definition:
Fahrenheit is a temperature scale where the freezing point of water is 32°F and the boiling point is 212°F at standard atmospheric pressure.
History:
Created by Daniel Gabriel Fahrenheit in 1724. Originally based on the temperature of a mixture of ice, water, and ammonium chloride.
Common Uses:
- Weather reports in the United States
- Cooking and baking in American recipes
- Medical thermometers in the US
- HVAC systems in North America
- Industrial processes in the US
Fun Fact:
Fahrenheit originally set 0°F as the coldest temperature he could create in his lab using a mixture of ice and salt! The human body temperature was originally set at 96°F in his scale.
