What does this tool do?
Kelvin is an absolute temperature scale that starts at absolute zero, so it has no negative values. This converter handles Celsius, Kelvin and Fahrenheit input and rejects values below absolute zero.
The Formula
K = °C + 273.15; °F = °C × 9/5 + 32; °C = K − 273.15Frequently Asked Questions
Why is there no degree symbol on kelvin?
Kelvin is an absolute scale, so the unit is written simply as K. The degree symbol is used for Celsius and Fahrenheit, which are relative scales.
What is absolute zero in Fahrenheit?
Absolute zero is 0 K, −273.15 °C or −459.67 °F. Inputs below that value are rejected because they are physically impossible.
