About Degrees Fahrenheit to Degrees Celsius
This converter turns degrees Fahrenheit into degrees Celsius as you type, and works the other way too: type in the degrees Celsius box to convert back. To convert degrees Fahrenheit to degrees Celsius, use the formula °C = (°F − 32) × 5/9. For example, 0 °F is -17.77778 °C, and 86 °F is 30 °C.
Temperature scales start from different zero points, so you cannot convert them with a single factor. Each conversion adds or subtracts an offset as well as scaling. Both units have exact definitions, so the converter gives an exact result, rounded only for display. Use the table below for common values, or set the decimal places to round the answer for a form or a label.
