About This Calculator
This converter translates any temperature between Celsius, Fahrenheit, and Kelvin using the standard formulas (linear conversions around the freezing/boiling points of water).
All three scales are always shown beside your target so you can read the equivalent temperature in every unit at once. Conversion runs entirely in your browser.

Frequently Asked Questions
What is the relationship between the scales?
They differ by scale size and offset. Freezing water is 0°C / 32°F / 273.15 K and boiling is 100°C / 212°F / 373.15 K, so a 1°C step is 1.8°F and 1 K.
Can Kelvin go negative?
Absolute zero is 0 K (−273.15°C). Negative Kelvin values are physically meaningless, though the tool will still perform the arithmetic if you enter one.
