Temperature Converter
Celsius, Fahrenheit, and Kelvin, converted into each other.
Temperature Converter is a free tool that runs entirely in your browser, with no data ever sent to a server. Convert a temperature between Celsius, Fahrenheit, and Kelvin.
What it's for
Understand a temperature shown in Fahrenheit on a US website, convert a scientific value to Kelvin, or simply check a thermostat.
What this tool does not do
This tool only applies the calculation described, with no check on the context of use. No limit is set by the tool itself; the only constraint is your device's memory.
Frequently asked questions
Why does Kelvin never have a negative value?
Kelvin starts at absolute zero (-273.15°C), the lowest possible temperature. A negative Kelvin value has no physical meaning, so the tool flags it if the calculation leads there.
