Temperature Converter
Convert between Celsius, Fahrenheit, and Kelvin
What is the Temperature Converter?
Written and maintained by the BitConvert team · Feb 27, 2026
The BitConvert Temperature Converter moves values between the three most widely used temperature scales: Celsius, Fahrenheit, and Kelvin. Type a number into any field and the other two scales update at the same moment, so you always see all three side by side.
Conversions follow the exact formulas rather than rough approximations: Fahrenheit equals Celsius times 9/5 plus 32, Kelvin equals Celsius plus 273.15, and the reverse formulas apply going the other way. That means familiar reference points land precisely, from water freezing at 0 degrees Celsius (32 degrees Fahrenheit, 273.15 Kelvin) to absolute zero at 0 Kelvin (minus 273.15 degrees Celsius). Everything runs in your browser with no rounding surprises, and each converted value can be copied to the clipboard with a single click.

Common Use Cases
Convert oven and cooking temperatures between Celsius and Fahrenheit when following a foreign recipe. Read overseas weather forecasts in the scale you know. Translate scientific data into Kelvin for physics and chemistry work. Check body-temperature or thermostat readings between Celsius and Fahrenheit when traveling between countries that use different scales. Convert freezer, refrigerator, and air-conditioning settings between scales, and interpret material or engineering specifications given in Kelvin against everyday Celsius values.
