Kelvin to Fahrenheit

Type a temperature to convert it from Kelvin to Fahrenheit. The two scales do not share a zero, so the conversion shifts as well as scales.

Result

Kelvin and Fahrenheit, side by side

Kelvin and Fahrenheit measure the same thing on different scales, and they start counting from different places. That is why the conversion is not a simple multiplication: 0K comes out as -459.7°F, not zero.

Going the other way, 0°F is 255.4K. Any converter that treats this as a ratio gets both directions wrong.
