Temperature conversion is essential for cooking, travel, science, and weather. Our Temperature Converter instantly converts between Celsius, Fahrenheit, and Kelvin using precise formulas.
Temperature Converter
Convert temperatures between Celsius, Fahrenheit, and Kelvin.
How the Temperature Converter Works
Three temperature scales, precise conversions:
Celsius to Fahrenheit: °F = (°C × 9/5) + 32
Fahrenheit to Celsius: °C = (°F − 32) × 5/9
Celsius to Kelvin: K = °C + 273.15
Kelvin to Celsius: °C = K − 273.15
Example: 100°C = 212°F (boiling point) and 0°C = 32°F (freezing point).
Frequently Asked Questions
What’s absolute zero?
Absolute zero (0 K or -273.15°C) is the theoretical lowest possible temperature where all molecular motion stops.
Which countries use Fahrenheit?
The United States, its territories, and a few Caribbean nations use Fahrenheit. Most of the world uses Celsius.
Pro Tips
- A quick estimate: 30°C is roughly 86°F, and 0°C is 32°F
- For oven temperatures, 180°C ≈ 350°F (common baking temperature)
- Kelvin is used primarily in scientific contexts
