Convert between Celsius, Fahrenheit, and Kelvin.
About Temperature Conversion
This tool converts between °C, °F, and Kelvin using standard formulas, entirely in your browser.
About this Temperature Converter
Convert between Celsius, Fahrenheit, and Kelvin quickly and accurately. Temperature uses different formulas than simple multiplication—this tool applies the correct equations so you get precise results. Use it for weather (e.g., converting a forecast), cooking and baking (recipe temperatures in °C or °F), travel (understanding local temps abroad), or science and labs (Kelvin). All conversion runs in your browser with no server uploads. Enter a value and choose source and target scales to see the result instantly.
Key Features
Celsius (°C), Fahrenheit (°F), and Kelvin (K)
Instant conversion using correct formulas (not simple ratios)
Bidirectional: convert from any scale to any other
Copy result for use in documents or recipes
Accurate formulas: °F to °C uses (F − 32) × 5/9; K = °C + 273.15
Runs in your browser; no account needed

Popular Use Cases
Weather: convert forecasts or historical data between °C and °F
Cooking and baking: convert recipe temperatures (e.g., 180°C to °F)
Science and labs: work with Kelvin and Celsius
Travel: understand local temperature units when abroad
Tips & Best Practices
Water freezes at 0°C / 32°F and boils at 100°C / 212°F. Kelvin = Celsius + 273.15; 0 K is absolute zero.
Room temperature is about 20–25°C (68–77°F).
For quick °C to °F mental math: double °C, add 30 (approximate).
Frequently Asked Questions
How do I convert Fahrenheit to Celsius?
Use the formula: C = (F − 32) × 5/9. Or use this tool: enter the temperature in Fahrenheit and select Celsius as the target.
What is Kelvin used for?
Kelvin is the SI unit for temperature, used in science and engineering. 0 K is absolute zero. Kelvin = Celsius + 273.15.
Why is the formula different from other unit converters?
Temperature scales have different zero points and step sizes. Celsius and Fahrenheit use offset formulas; Kelvin shares the same step size as Celsius but has a different zero.
