How to convert degrees Fahrenheit to degrees Celsius
Use the formula °C = (°F − 32) × 5/9. Temperature scales have different zero points, so you cannot simply multiply by a single factor.
°C = (°F − 32) × 5/9
Example
To convert 98.6 degrees Fahrenheit to degrees Celsius: apply the formula above = 37 °C.
