Fahrenheit to Celsius (°F to °C)
Formula: °C = (°F − 32) × 5/9
How to convert degrees Fahrenheit to degrees Celsius
°C = (°F − 32) × 5/9
Example: (98.6 − 32) × 5/9 = 37, so 98.6 °F = 37 °C.
Fahrenheit to Celsius is needed for American recipes and oven settings: 350 °F is about 177 °C and 400 °F about 204 °C.
A normal body temperature of 98.6 °F is 37 °C; a fever starts at about 100.4 °F (38 °C). To estimate, subtract 30 and halve the result.

What is a degree Fahrenheit?
On the Fahrenheit scale water freezes at 32 °F and boils at 212 °F, so there are 180 degrees between the two points instead of 100. It remains the everyday scale in the United States.
What is a degree Celsius?
On the Celsius scale water freezes at 0 °C and boils at 100 °C at sea-level pressure. It is used for weather, cooking and medicine in nearly every country except the United States.
Frequently asked questions
How do I convert degrees Fahrenheit to degrees Celsius?
Use the formula °C = (°F − 32) × 5/9. (98.6 − 32) × 5/9 = 37, so 98.6 °F = 37 °C.
What is 450 °F in °C?
450 °F = 232.2222 °C.
How do I convert degrees Celsius back to degrees Fahrenheit?
Use the inverse formula °F = °C × 9/5 + 32, or open the Celsius to Fahrenheit converter.
