Frequently Asked Questions
What is the Kelvin scale?
The Kelvin scale is an absolute temperature scale where 0 K is absolute zero, the theoretical lowest temperature possible.
Why subtract 273.15 to convert Kelvin to Celsius?
Because 0 K is absolute zero, which is -273.15°C, the difference between the Kelvin and Celsius scales is 273.15.
Can I input negative Kelvin values?
No, the Kelvin scale starts at 0 K (absolute zero), so negative values are not physically meaningful.
