How to convert degrees Celsius to degrees Fahrenheit
Weather forecasts, oven settings and body temperature: the US uses Fahrenheit, almost everywhere else uses Celsius.
To convert degrees Celsius to degrees Fahrenheit, use °F = °C × 9/5 + 32. Temperature scales have different zero points, so the conversion adds an offset as well as scaling — multiplying alone gives the wrong answer.
Celsius (°C): K − 273.15. Fahrenheit (°F): °C × 9/5 + 32.
For the opposite direction, use the Fahrenheit to Celsius 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.
