Convert Kelvin to Fahrenheit
Input the number of kelvin you want to convert to fahrenheit.
How to Convert Kelvin to Fahrenheit
The kelvin and fahrenheit are both units of temperature measurement. To convert kelvin to fahrenheit, use the formula °F = (K - 273.15) × 9/5 + 32.
Formula
Step-by-Step Example
Convert 100 K to fahrenheit:
Formula: °F = (K - 273.15) × 9/5 + 32
100 - 273.15 = -173.15
-173.15 × 9/5 = -311.67
-311.67 + 32 = -279.67
100 K = -279.67 °F

About These Units
Kelvin (K)
Kelvin (K) is the SI base unit for temperature, used in science and engineering. Absolute zero (0 K) is -273.15°C or -459.67°F—the coldest possible temperature where molecular motion stops. No degree symbol is used with Kelvin. Water freezes at 273.15 K. Named after Lord Kelvin.
Fahrenheit (°F)
Fahrenheit (°F) is the temperature scale used in the United States for weather, cooking, and daily life. Water freezes at 32°F and boils at 212°F. To convert Fahrenheit to Celsius: °C = (°F - 32) × 5/9. Normal body temperature is 98.6°F. Named after German physicist Daniel Fahrenheit.
