About the fahrenheit to celsius conversion
The fahrenheit (°F) and the celsius (°C) are both units of temperature. Convert between temperature scales — Celsius, Fahrenheit and Kelvin.
Unlike length or weight conversions, temperature scales have different zero points, so the conversion is not a simple multiplication — the converter uses the exact offset-and-scale formula automatically.
