Temperature Converter
Convert temperatures between Celsius, Fahrenheit, Kelvin, and more using Tooloria’s temperature converter.
About Temperature Converter
Recipes call for 375 °F, science journals use kelvins, and weather apps switch between Celsius and Fahrenheit at the drop of a hat. Tooloria’s Temperature Converter translates between Celsius, Fahrenheit, Kelvin, Rankine and Delisle with zero server round-trips. A two-way slider makes it easy to see how small changes in one scale reflect in another—handy for sous-vide cooking or thermodynamics homework. Precision extends to tenth-degree increments, but you can round to integers for quick mental checks. Swap units instantly, copy results or pin them to a three-item history sidebar for side-by-side climate comparisons.
Frequently Asked Questions
Why does water boil at 99.97 °C in the tool?
The default pressure is sea-level standard (101.325 kPa). You can enable ‘altitude mode’ to adjust boiling points based on local barometric pressure.
Can I convert a temperature range?
Yes—enter the lower bound, note the result, then type the upper bound. A future update will allow range inputs in one line.
Do you show negative Kelvin values?
No. Kelvin starts at absolute zero. If you enter a conversion that would imply a negative Kelvin, the tool flags it as out of range.
