Fahrenheit to Celsius Formula
°C = (°F − 32) × 5/9 (°F = (°C × 9/5) + 32)
Normal human body temperature is 98.6 °F (37 °C). The two scales meet at −40° (−40 °F = −40 °C).

About Fahrenheit and Celsius
Fahrenheit sets 32° at water's freezing point and 212° at boiling. The customary scale for weather and cooking in the United States.
Celsius sets 0° at water's freezing point and 100° at boiling (at sea level). The metric standard used by science and nearly every country.
Frequently Asked Questions
What is the formula to convert fahrenheit to celsius?
°C = (°F − 32) × 5/9. To convert back, use °F = (°C × 9/5) + 32.
32 °F = 0 °C — how do I convert other values?
Type any value into the converter above; it applies the offset formula automatically, handling the different zero points of the two scales.
Why can't I just multiply to convert temperature?
Because fahrenheit and celsius start at different zero points. Normal human body temperature is 98.6 °F (37 °C). The two scales meet at −40° (−40 °F = −40 °C).
