Conversion formula
T(°C) = (T(°F) − 32) × 5 / 9
T(°F) = T(°C) × 9 / 5 + 32
How to convert Fahrenheit to Celsius
Apply this formula to the temperature value: T(°C) = (T(°F) − 32) × 5 / 9. Scales can have different zero points; multiplying by one factor is not always enough.
For example, 1 °F = -17.222222222222 °C and 10 °F = -12.222222222222 °C.
What is Fahrenheit?
Fahrenheit (°F): Common in US weather reports and some ovens. Conversion to Celsius requires subtracting 32 before scaling. 32 °F = 0 °C; 212 °F = 100 °C.
What is Celsius?
Celsius (°C): Used for weather and everyday temperature readings. Its interval size matches kelvin, but its zero point differs. 0 °C = 273.15 K.
