Fahrenheit to Celsius Converter

The Fahrenheit to Celsius Converter transforms temperature values from the Fahrenheit scale to the Celsius scale using the standard formula: subtract 32 and multiply by 5/9. Fahrenheit is the primary temperature scale in the United States, while Celsius is used by most of the world and in all scientific contexts.

This tool is useful for travelers arriving in the US who need to interpret weather forecasts, for anyone reading American recipes that list oven temperatures in Fahrenheit, for medical professionals converting body temperature readings, and for engineers working with equipment specifications from American manufacturers.

Enter any temperature in Fahrenheit and the tool displays the Celsius equivalent instantly. The result is rounded to six decimal places with trailing zeros removed. Key reference points include 32 degrees Fahrenheit equaling 0 degrees Celsius (the freezing point of water) and 212 degrees Fahrenheit equaling 100 degrees Celsius (the boiling point of water).
