How to convert degrees Fahrenheit to degrees Celsius
Reading US weather, recipes and thermostat settings in Celsius.
To convert degrees Fahrenheit to degrees Celsius, use °C = (°F − 32) × 5/9. Temperature scales have different zero points, so the conversion adds an offset as well as scaling — multiplying alone gives the wrong answer.
Fahrenheit (°F): °C × 9/5 + 32. Celsius (°C): K − 273.15.
For the opposite direction, use the Celsius to Fahrenheit converter. All temperature units are on the temperature converter.
Limitations
- Results are rounded to the decimal places you choose; the calculation itself keeps full precision.
