Fahrenheit to Celsius Calculator
Enter a temperature in degrees Fahrenheit to convert it to degrees Celsius.
Fahrenheit to Celsius Formula
To convert Fahrenheit to Celsius, subtract 32 from the Fahrenheit value and multiply by 5/9.
Formula: °C = (°F - 32) × 5/9
For example, 77°F becomes 25°C.
That formula is widely used because Fahrenheit and Celsius use different reference points and step sizes. Converting directly with a calculator is much safer than relying on rough estimates when precision matters.
