Fahrenheit to Celsius Converter
Fahrenheit is the everyday temperature scale in the United States — weather reports, cooking, thermostats — while the rest of the world reads Celsius. Converting Fahrenheit to Celsius helps travelers decode a 75°F forecast, cooks follow American recipes, and anyone comparing climate data across countries. The formula is °C = (°F − 32) × 5/9: subtract 32 first, because Fahrenheit’s zero sits 32 degrees below freezing. The converter above computes it instantly both ways, the table shows common weather and cooking temperatures, and the FAQs explain key reference points like body temperature.

Frequently Asked Questions
How many celsius are in 98.6 fahrenheit?
98.6 fahrenheit = 37 celsius. Just apply the conversion to any value with the converter above.
What is the formula to convert fahrenheit to celsius?
To convert fahrenheit to celsius, subtract 32 from the Fahrenheit temperature and multiply by 5/9. In short: °C = (°F − 32) × 5/9.
What is 98.6°F in Celsius (body temperature)?
98.6°F equals 37°C — the long-quoted average human body temperature. (98.6 − 32) × 5/9 = 66.6 × 5/9 = 37°C. Modern research suggests the average is slightly lower, but 37°C remains the standard reference.
How do I convert celsius back to fahrenheit?
Simply reverse the math: to go from celsius to fahrenheit, use °F = °C × 9/5 + 32. Or use our dedicated Celsius to Fahrenheit converter.
