Convert degrees Fahrenheit to degrees Celsius instantly. 25 °F = -3.888889 °C.
1 °F = -17.22222 °C
To convert degrees Fahrenheit to degrees Celsius, use the formula °C = (°F − 32) × 5/9. Temperature scales do not share a zero point, so the conversion uses this exact formula rather than a single multiplier. For example, 25 °F equals -3.888889 °C.
