The formula
Celsius is found by subtracting 32, then scaling by 5/9:
°C = (°F − 32) × 5/9
Reversed, °F = °C × 9/5 + 32.

Frequently asked questions
- How do I convert Fahrenheit to Celsius?
- Subtract 32, then multiply by 5/9. For example, (98.6°F − 32) × 5/9 = 37°C. The converter above computes this live as you type.
- What is the Fahrenheit to Celsius formula?
- °C = (°F − 32) × 5/9. The −32 removes the Fahrenheit zero-point offset, and the 5/9 rescales the degree size to Celsius.
- What is a 98.6°F body temperature in Celsius?
- 98.6°F is exactly 37°C, the commonly cited average human body temperature.
- What is a 350°F oven temperature in Celsius?
- 350°F converts to about 176.7°C ((350 − 32) × 5/9), often rounded to 180°C on oven dials and recipes.
- At what temperature do Celsius and Fahrenheit match?
- At -40 degrees exactly — -40°F equals -40°C, the one point where both scales agree.
- Is any temperature I enter uploaded or saved?
