Conversion formula
°C = ((°F × (5 / 9)) + (45,967 / 180) × (1)) − (273.15)25 °F ≈ -3.88889 °C
degree Fahrenheit (°F)
Fahrenheit uses °C = (°F − 32) × 5/9; 32 °F = 0 °C and 212 °F = 100 °C.

Frequently asked questions
How many degrees Celsius are in 25 degrees Fahrenheit?
25 °F ≈ -3.889 °C. °C = ((°F × (5 / 9)) + (45,967 / 180) × (1)) − (273.15)
How do I convert °F to °C?
°C = ((°F × (5 / 9)) + (45,967 / 180) × (1)) − (273.15)
Why does this conversion need more than multiplication?
Temperature scales have different zero points. Apply the scale and offset in the formula; below absolute zero is a mathematical result only.
